I did not mean to ruffle too many feathers. The best example I can give you is I had a Fleetwood Fiesta LX, 37 feet long, V10, 362HP. Towing 5000#s I could go up hill accelerating with no problems anywhere. My 2007 Alfa See Ya Cat C7 350HP towing 5000# would not pick up any speed when going uphill.
If I put my foot down, the gasser would take off much faster, no matter what.
I understand the Alfa is heavier, but the gasser was no slouch. I believe there is an outdated concept that all diesels are better. I believe that once you go over 400HP and 1000# of torque diesels are faster, but the gassers have improved so much that they can compete with no problems.
Why do I have Diesels? Simple: rear engine, no noise, ride quality.
Also speed limit. The F53 is limited to 75. I don't drive that fast, but the transmissions in the F53s are doomed thanks to the governor. You put the foot down, it down shifts and once it hits 75 it stays there, revving at 5000RPM. This will kill the tranny pretty fast.
One last thing, I did not buy a new RV every year, I owned an RV rental company and we had a fleet. I have seen the RVs go through 200K on both types of engines trouble free. As a matter of fact, I had a V10 in a class C with 300K, all original.
To the OP, my advise is make your decision based on ride quality, handling, noise and layout, not fuel type. Diesels cost twice as much to maintain. Unless you are buying something with over 400HP, power is not much of a difference anymore
