Of course I am a little biased because I own one on a
Chevy Chassis but when I was looking for my next RV I test drove more than a dozen RVs of the same model,Fleetwood 26Q.
All on the Ford Chassis,as I said in the Thread I linked, the one on a Chevy Chassis was a much better choice for me.
If I ever decide to buy a replacement for the one I have now I will look for one on a Chevy Chassis.
If you can, I would suggest if you can find the one that would work for you and it is offered on both chassis,try them.
So sorry to hear about your loss of your RV.
Good Luck in your quest for that new RV
