We're toying with the idea of a Class A RV. Sometimes we'd want to tow the H3. I haven't any experience with pushers or flat towing. Salesmen just tout hitch ratings, but that means nothing related to the engine or trans capability. I'm thinking of those long grades in 110 degree heat.

Two prime question are:
How's the H3's towability?
How can I determine whether a pusher's drivetrain and brakes can handle it?

Suggestions and recommendations would be appreciated.

 

I asume you are talking about a diesel pusher and in that case it can handle the H3.I have towed a lot larger behind my class C with a 460 gas engine. As for towability of the H3 IMO would be no different than any other SUV. Just make sure to read the owners manual on how to prep the 3 for towing Happy RV.ing

 

My inlaws tow a jeep liberty behind their Class A Gasser so an H3 behind a diesel should be no issues. Always keep in mind though that you have a lot of weight extra riding on those RV brakes
