Welcome to the Sportscoach Technical Info page.

This page is intended to share technical information on problems encountered by owners of Sportscoach motor homes. This information could be helpful tips, howto's, repair info or other similar data. At the end are links to general RV tech sites. Many have good generic information. Links to additional Sportscoach information are at the end of this page. I am very fortunate to have former Sportscoach people contact me who have offered their technical assistance and expertise. Many of us are available on Yahoo at the Vintage Sportscoach group. If you have questions, send email to the group and we will gladly help. If you need info specific for Coachmen produced Sportscoaches, you can contact Mel Williams at Coachmen Industries. Mel's number is 574-825-7000.

The VSO has been contacted by MasterTech OEM of Elkhart, In. They have been dealing with Sportscoach for over 15 years and took over the Sportscoach parts and service number 574-522-6224 almost 6 years ago . They say there is little they cannot get or mfg! Just take a look at the Before and After pictures of this 1992 CrossCountry that was involved in an accident with a semi. From Doors - Windows - Siding - Windshields - Grills - Bumpers - Moldings - Chassis AC - Holding Tanks - Fuel Tanks - Etc. Email Timthervman at Mastertech OEM for the hard-to-find Sportscoach windshield gasket kits if you need them. Update as of 2/19/2005 they have a new 22,000 sq ft facility at 28717 Holiday Place, Elkhart, IN 46517. Please make note!


Another source has been found for Sportscoach windshield gaskets. Austin Hardware Company, 800-634-4293. 1 piece gaskets are part #AS1536 and 2 piece gaskets are part #AS1488. Available in 50' rolls only for around $70 plus shipping. The 50' roll will make 2 complete gasket sets.


Sportscoach III owners, the mystery of the missing circuit breakers has been solved! Thanks to Bob Bishop, he found a secret sliding panel located just below the builtin night tables next to the bed. Look directly at the one with the switches for selecting which A/C operates. Just below those switches is a hidden panel. Push on it just right and the panel "pops" to revel the circuit breakers.


The following tip comes from Bob Redditt.

When we got our Sportscoach, the Door lock wouldn't work. I found that the groove in the slide plate had been bent and widened from repeated stress over the years. The barrel that you pull & push on the inside of the door was supposed to block the slide plate when you push it in thereby locking the door. However, because the slide plate had been stretched out the barrel wasn't big enough to block it anymore. Solution:

  1. I went to the hardware store and got a brass bushing a little bit bigger around than the original barrel.
  2. Found a long bolt that threaded into the same hole that I took the barrel out of.
  3. Thread a nut about 1/2 way up the bolt.
  4. Slide the Brass Bushing on the Bolt snug against the nut.
  5. Thread the bolt in the lock.
Now, when I push in the bolt or key lock from outside, the door locks solidly. I'm going to dip the bolt in some Plastikote (like used on tool handles). A new lock costs over $100.00. Saved a bundle.

This tip is a lead on good replacement baggage door locks. John Hissink has a Sportscoach IV and according to Coachmen, the locking type compartment door lock is P/N 474584. They are available from Freeway Easy Living, Banning, Ca 909-849-6785. The non locking unit is P/N 474585.


The following info comes from Jere Duke, formerly of SCA.

Radiator hose replacements: Go to a parts store that has: knowledgeable people that are willing to LOOK, and a Goodyear hose catalog. Goodyear appears to be the only company that has a competent catalog relating to motor homes. Take your old hose with you along with the make and chassis type Dodge M500, Chevy P30, etc., + the engine size). Use the chassis year if the chassis year and the coach model year are different. The only other choice if you cannot find the correct hose is to fabricate one out of some sort of tubing (stainless best but exhaust pipe in a pinch will do) and use shorter pieces of radiator hose to finish it up. NAPA does NOT have a good listing of these parts. One other thing: NAPA does not list a 1973 chassis with a 454, only a 350. And just because NAPA says so doesn't necessarily mean it is so. I have a '73 chassis (with '73 brakes......different and much more expensive in '74 and later) with an original 454.


Here's another readers comments on the GM hoses. This info comes from Bob Smejkal.

I had a friend that is a GM parts manager do some research and some of the original factory hoses for the mid 70's are still available. My chassis was built on 6-75, and home on 9-75. The title lists it as a 1976. Both radiator hoses for my MH were still available from the factory. The top hose is part #6259953 and the lower or bottom is #343414. According to my research the 6259953 fits 1973-1981 454 motor home chassis. The 343414 fits 1974-1981 350 & 454cu in. It is also listed for 1982 350cu in units. The 343414 (lower) makes a 180 degree turn around a frame crossmember and would be difficult at best to fabricate. Both of these part numbers were a perfect fit on my unit. Hopefully this information may be of some value to others.


Have you had any problem with rain leaking in thru the top of the coach door. It can and WILL happen if the caulking that seals the rain "gutter" above the doorway has fallen off. Make sure you check this when you do your fall or spring inspections.


If you need to replace your Trucklite model number STI-71 rear lights, they are replaced by Grote part number 52892. The units are sealed and you cannot replace just the bulb. Pop the entire assembly out of the rubber gasket and replace with the new one. Easy job and about $10 for the part.

The upper freezer door hinge broke on my Dometic refrigerator. I checked with Camping World and other sources and was told my only solution was to buy a complete door for $150 or so. Not liking this answer I called Dometic. They said that kits are available to repair all of the door hinges and are available through All Seasons RV Appliance Parts & Service in Elkhart, IN. You can reach them at 800-348-7697 or 800-344-0673. The upper and lower hinge repair kit cost $18.95, can be charged to a credit card and shipped anyway and any place that you want. Since having this occur I have talked to two others that have paid for a full door ($350 or so) as well as a freezer door. This company is a valuable resource for us to know about.


Just wanted to post this in case anyone has an electrical short (blown fuse) problem they are trying to fix in their rig. Use a simple test device consisting of a 12V bulb wired across the fuse receptacle. My particular problem was with the tail light circuit. So I picked up a 12 Volt halogen bulb at Radio Shack, used crimp connectors to attach a 10 foot section of wire to each lead, then crimped on a couple of spade connectors to the other ends of the wires. I plugged the spades into the fuse receptacle and turned on the headlight switch. The bulb glowed. Then I started shaking wires, watching the brightness of the bulb. It took about 30 seconds to find the problem. Somewhere in the RV's past, some knucklehead in an RV service Dept. had spliced into the 12V supply for some yet unknown reason. He ended up shorting the 12V positive to ground. As I shook wires, the light changed intensity. Didn't take long to figure out where the problem was. One step closer to the road.


The gas filler plastic recess part number is 610 for Sportscoach, don't remember the wholesale catalog, but if you call RVS Corp. at 408-779-3173 they will know what one is looking for. They also have an 800#, don't know if it works outside CA, but is 800-821-2266. Their address is 10900 Monterey R. Morgan Hill, CA 95037. Thank you Gerry Ducey for this information.


And now the $64,000.00 question: I'm beginning to see signs of corrosion on the aluminum sides of my coach, how do I fix it? I spoke with some very good repair folks regarding this problem. You cannot separate the sides from the bond beam. You have to cut the siding underneath the bond beam and separate it from the foam backing. A new piece is then laminated to the foam. There is a widely held belief that the fasteners used by SCA are causing the aluminum to corrode. This is entirely FALSE! Aluminum will corrode from exposure to the elements over time. The repair is expensive if it is to be done right. Once you make the repair, treat the coach with an anti-corrosive treatment similar to what is used on airplanes. Now it will outlast you!


Owners of 1980 -1989 Pathfinders and Cross-Country coaches, if you need wiring diagrams or other technical info that the VSO cannot provide, please call Mel Williams, SCA Service 574-825-7000. Mel will do his best to help you. Please tell him Bob Spear from the VSO referred you. Mel works at Coachmen Industries and has access to extensive data for these coaches.


Wes Johanson sends the following info for owners of Cross Country Sportscoaches. The seller told me the Generac generator stopped putting out full power. He had several service people look at it and some tried to diagnose over the phone. After helping to rewind the rotor AND the stator and check out the Briggs engine, one service man found the kill switch was shorting under load on one side only. Replacing the kill switch seems to have solved the problem. Note* the L.E.L. sensor in the kitchen seems to draw significant battery power. If there seems to be an abnormal draw, check this.


The Travco Mailing List welcomes any Sportscoach owners with a Dodge Motorhome Chassis who may wish to join. There are many common interests between Travco and Sportscoach owners especially related to the Dodge Chassis/Power train.


Here's some important info I've dug up regarding original equipment suppliers for Sportscoaches. Some of the companies may not be in business or be able to supply replacements but the info is good to know. I will try to mark the businesses no longer available in orange.
