The only caution I will give is this: Watch your tow ratings and CGVW lmits.
Though I have seen folks tow way more than they should and get away with it.
I do suggest you watch those figures... I can see where a proper toy hauler with a car in the garage could easily put you over both the hitch rating and the CGVW of the motor home. And that .. Can lead to problems down the road.
What kind of problems?
Well, if you rear end someone... Legal, and Financial
And Transmission
And brakes
And engine
And.. Well you start to see the issues.
IN all cases, expensive.
