Class A Towing capacity

Your limiting factor will usually be the hitch capacity. Plus, it's usually not pulling the trailer that's the problem, it's stopping it. If your chassis is not set up to tow that amount, then don't! The engine size is a factor, but usually not as much as the chassis/suspension/braking system. Of course, a diesel engine produces more torque easier than a gasoline engine which is better for towing, but again, if you can't stop the load once it's moving, you're in much more trouble!

I apologize as I'm sure this topic has been discussed in the past! We are looking at buying our 1st Class A motorhome(33ft-36ft) but not sure if we should go diesel or gas. At times we will be pulling 5,000-6,000lb trailer and not sure if the gas RV will be able to handle that much. Pretty much just traveling through flatland and smaller hills(no mountains). Thanks for any advice!

a Class III hitch has a max weight load of 5,000-lbs while a Class IV hitch is rated at 10,000-lbs. I don't know of any Class A gassers that have a Class IV hitch but some diesels do.

I would weigh trailer loaded with your normal weight. You are at or above most gas MH tow cap.
