Here is my opinion. If the Class A Gas MH weighs more than 15,000 pounds I wouldn't do it. Not that you can't do it. But it is just because it would drive me crazy to drive a slug like that. Uphill would be frustrating. Downhill would very nervous. Downshifting will be your friend going downhill. Keep off the brakes as much as you can.
What is your rear gear ratio? Hope it is 4:56 or lower.
