We tow our boat with an RV. The thing you have to be looking for is what each RV can tow. Most, and I repeat most Class C motorhomes are only rated to pull 3500 lbs. This is based upon the tow hitch and the GCW rating. Most Class A motorhomes tow 5000lbs and up. This is also based on the tow hitch and the GCW. If it is a Diesel you can tow even more typically. Here is what you need to do
-Check the tow rating on the hitch. You will need 5000lbs or better if you are towing that Malibu in your profile
-Check the GW of the vehicle
-Check the GCW of the vehicle
(these will be listed on a sheet of paper in one of your cupboards or closets probably)
Take the GW of the vehicle + all of your people weight, water weight, fuel weight, supplies, etc = x weight.
-Subtract that weight from the GCW and that tells you what that motorhome can safely tow...
For example our motorhome weighs 14,000lbs and the GCW is 21,500.
I take the 14,000 + all the weight we have on board and lets say it is 2000 lbs. So I have to take 21,500 - 16,000 and that leaves me with 5,500 lbs. My hitch is rated for 5,000 lbs.
Hopefully this makes sense
