Increasing towing capacity

The GCVW (Gross Combined Vehicle Weight) is the maximum amount of weight that the chassis and BRAKES were designed to handle. Exceeding that may mean that in an emergency the brakes on the RV may not be able to stop soon enough. I don't think any recommendation can be made without the vehicle being loaded as it would be during travel and then just doing some basic calculations. Then the loaded coach weight PLUS the loaded Jeep weight are added and if it is less than the GCVW you should not have any issues. DO NOT accept the manufacturer's weight for the coach or the Jeep. Have them weighed exactly as they would be when you travel. Keep in mind that you may be able to adjust your coach and Jeep weights if you do not fill their fuel tanks completely. Sort of a hassle but if traveling with a 1/2 full tank makes you legal, then you do it. The same goes with waste and fresh water tanks. There are a lot of ways to adjust your weight but without knowing the exact weights you have no place to start.
