RV Longevity - My experience

OK, so after 14 different motorhomes, of which 8 were my own rental fleet, I decided to post a few things I learned:
Life expectancy in miles: I have heard several people saying how many miles is too many. Well, I have sold RVs with over 300K miles, rentals, still with the original transmission and engine. Heck, even the factory AC compressor. You may wonder how? Maybe the right maintenance? Well, 3 of my units are Cruise america ex-rentals, one of them I got with 150K and got to 302K miles with no problem.
Transmission: FOLLOW TRANSMISSION MAINTENANCE SCHEDULE!!!! I spent 15 years in the automotive industry and now I am in aerospace. The people that tell you not to service the transmission don't know what they are saying, or they are the ones who will charge you to rebuilt it.
Generators: Onan 4000 microquiet are the only choice for small units, unfortunatly. Their quality has gone down significantly. 7 of my units were brand new, 5 with the 4000W. In ALL they had to change the fuel pump before 500 hours. In ALL they had to change carb before 1000 hours. I have run 4000W to 1800 hours and blew the engine. Meticulously maintained, made no difference. The other Onan, gas or diesel, are much better designed, they will last longer. I have a class A with a 5500 Onan with 3500 hours, no problem. Another note: low use generators are just as bad. Once to get to use them they start to loose systems one by one. Generac: They don't make them anymore. I always had good luck with them, they run better than Onans.
Tires: Put good tires, have them checked. Once you have cracking, tires 7 years old or 40K miles; just change them. If you lose a tire you will damage your RV.

To sum it up, I chose ford in all my units because I know the designers of the powertrain and it is bulletproof. Sprinter or Dodge diesel chassis? Not in a million years. Y spent some time in the Mercedes factory and have seen the cut-away chassis being built. If something goes wrong, you are dead. GM Chassis? Never tried. Diesel pushers? Great RVs, but longevity being better in diesel engines does not affect me, I get 300K with the gas.

Hope it helps!
