I am looking to buy my first RV. Front runner is a Class C with 5,000 lbs towing capability. I want to be able to tow my Jeep Wrangler Unlimited as a dinghy. Gross Vehicle Weight is 5450, Curb Weight is 4100, which do I use to determine if the MH can tow the vehicle?
Weigh the coach fully loaded and ready to go along with a people allowance. Subtract this weight from the rated GCWR. This is the max weight for the toad loaded.
Having said this, a good inspection of the hitch setup etc....will allow you to tow much more and if it's rating is limited by the transmission as in most cases, it may give you some problems on long 6% grades. If so, another 25% is to be gained, by limiting the speed to 25 mph in low gear for getting over the top. Otherwise the rig might go into limp mode and you'll be forced down to this speed anyway. Extra and/or larger tranny oil coolers and electric fans could help and a tranny oil temp. gauge would be a good investment as well.
We did 7200 miles with a good bit of it in the rockies this past summer in extreme heat for the most part and did pretty well. With flat and hilly terrain, I don't even know it's back there and it always runs strong anyway. Only burns another 1/2 MPG or so, with our 50mph cruising speed, too.
Whatever you do, make sure you have a good toad brake installed and wouldn't have any other than the READYBRAKE for simplicity, dependability and cost effectiveness. Again, just my HO and only worth what your paying for it.
