I had this problem, my clearance lights and tail light would not come, dash, head, turn and stop would work. check fuse and the clearance light fuse was blown, put a new fuse and it blew, so ( be careful doing this ) I put in a larger fuse and crawl under the MH and trace wiring, found that the wires to the tail light was getting hot, pull the fuse and I saw doing this that one of my clearance light was out, so I change out the light and every thing work ok. What had happen the bulb did burn out but it had shorted it self out inside, a direct short. never heard or had the dealer every heard of this. That MHing, you never know what next.
Mine did the same thing, found out ( if you have an outside vent ) that the screen was plug, I did not know it had a screen, but way in the back of that cabinet there is a little door or hole and reach down there and you will find a screen, I clean mine out and went from drying for 3 hours to 30 minutes, good luck.
Will I just change my oil, ( diesel gen and cummins engine), grease all fitting, recoated the roof, wax this 38 footer, put new batteries in, check air in tires, change a rear flat, check all lights, one clearance burn out, put in new Blu-ray, two new TV flat screen, new air filter, took out old ref. and installed new house type ref. removed day bed and put new lazy-boy chairs and clean inside. Getting ready to go to Canada for three months. OH by the way I am 80 and still going strong, I feel like 50, still joging 4 miles a day. Like someone said age is just a number. Please don't take my RV away from me.
Slide awning flapping: I took some PVC and made a box out of the PVC a little bit higher than the awning, then when with the slide out I sled the PVC box under the awning, this did two thing, it bowed the awning up, stopped the flapping and the rain did not puddle. I did not glue the joints so I could take it apart and store it in the storage area.
I have the same size tires, but my side wall state 110# not 80, mine are 6 years old with about 50,000 miles on and are still good, I will be changing them out this year just because of the 7 years, I will buy the Goodyear again, have had good luck so far
Mine is the 5.9 cummins in a 38 foot Newmar Mountain Aire 1998, I installed the bank system and solved my problem, just came back from CA. pulling my full size pickup and had the power to go over the mountains, also gave me 10+ MPG, it helped but it still not a hot rod, but I had all the time in the world, (Retired)
I had the same problem, no clearance lights/tail light. found out it was the fuse, mine is under the dash but have a removable door on top of dash, pull the three (3) fuses, one for day light ICC, one for night light ICC and one for all clearance lights, they all look good, so started looking for a broken wire, found none, when to the fuses and replace all three and it work, one of those fuse was not working, I think it was the main clearance light fuse,still working. It can be puzzle sometime, but that RVing. Good luck
We have 1998 Mountain 38 foot Newmar, it has 90,000 miles on it and we are traveling to Canada this summer, about 8000 miles, I keep it up and check all parts. I will have no problem traveling all over this country, Oh it's a front end diesel and I pull a 2004 GMC pickup full size, getting about 10 MPG, just keep ahead of all repairs and you will have no problems. Have FUN
I have 98 Newmar Mountain Aire 38 foot FRED, I did change out the tires to the 245/70 R/19.5 That was 6 years ago and have had no problems, It took out the over steering problem that I had with the smaller tires, go down the road straight now, they are Goodyear's. I installed the Bank System and have a 5 inch exhaust, this is giving me around 10 MPG. I also had a problem with the rear spring sagging on this 38 footer, I installed two 5000# coil spring, this has solved that problem, this I did 12 years ago. When owning a MH you have to be able to UPGRADE, the factory does make mistake, that frame should not have been put on a 38 foot MH,(Freightliner)
I completely strip my MH and used RedMaxPro #3, That was three years ago and it look better than when a I got it new back in 1998. I just wash it with Dawn soap and put another coat of RMP #3 every spring, I can put a coat now in about one hour and it's 38 feet long, best thing I ever did, thought WAXES just about killed this old man, ( will be 80 soon)
