Class "A" MH - Towing a Jeep Summit

Thank you all, and yes, towing the Jeep on its own wheels.

You're towing the Jeep on its own wheels, right?

If so it is putting very little stress on the coach. Not nearly what a 5000lb trailer would put on it. There is almost no tongue weight. It is a rolling load with very little wind resistance, and its own brakes.

Only worry you need to have is dropping down to 2nd or first gear over the big passes and generally a slow ride. Altitude is not your friend here. Otherwise fine.
Tow ratings on MHs like yours are generally based on available power left over after pushing a big box down the hiway with a drivetrain that doesn't have much to spare.

reko71, I totally agree with your statement, talked to some folks who have done exactly the same trip, and with almost the same scenario, the key is, take it easy in the mountains. My MH Maximum GVWR = 16000lb, Maximum GCWR = 23000lb and Maximum Trailer Weight = 7000lb, I also have installed "Roadmaster Invisi Brake System" in the Jeep, there will be no cargo in the Jeep and a very light weight in the coach with empty holding tanks and a bit of fresh water, but the fuel tank.
I like peoples input regardless of the topic, makes me sleep more easily.

I don't think anyone is going to be willing to tell you a straight yes or no answer cause as you stated you are actually over the tow limit for the RV, but obviously not by much. How do you know the true weight? If you had it weighed with a full gas tank you would probably be within the limit if your tank was only 1/4 full. Also no one wants to be caught recommending anyone go over any of the limits that our RV's were meant for but it is done fairly often, sometimes out of necessity and other times out of just not knowing. I was doing a military move and had to be weighed with the U-Haul trailer before and after loading and my weigh ticket at the end of my journey ended up showing that I had exceeded the weight limit for my hitch and for the trailer (oops). Currently my MH is at the weight limit if I have a full tank of water, or full holding tanks, which I don't usually have when traveling but if I plan to or have been boondocking I might be over for a short time until I can dump.
My concern with the altitude would be less on the engine and more on the braking. The altitude will obviously hurt the performance of the engine but I think it would still be OK, just slow going. The brakes though also have a tendency to have a harder time cooling with the thin air so watch that in the mountains too.
