Question, How much can I tow behind my RV?

Answer:

The lesser of

A. The rating of the hitch installed and rated by the RV manufacture

B. The gross combined weight rating (GCWR) minus the loaded vehicle weight of your RV

1. See your dealer or the ford towing guide to determine the GCWR of your RV

2. Weigh your RV loaded with fuel, water, personal items, passengers, etc. Many truck stops, sand and gravel supply, moving companies, etc. will weigh your coach for a nominal fee. Have them weigh the front and rear axles separately. Then verify the vehicles Gross Vehicle Weight Rating (GVWR) or any axle rating (see certification label on/near drivers door or seat) is exceeded.

3. Subtract loaded RV vehicle weight from GCWR. Compare result to installed hitch rating. The smaller number is what you can tow."



Here is what I got when I ran some numbers....

I took specs from the Forest River site for a Class C Sunseeker 2690S (because it's pretty light, not too long, still has 22,000 GCWR).

A. Let's say I replace 5,000 lbs. hitch with a 10,000 lbs. or 12,000 lbs. hitch...then...

B. Lets see:

1. 22,000.00 lbs.
2. Full 55 gal fuel tank (figured at 6.25 lbs per gallon) = 343.75 lbs.
Assume Fresh water(44g), grey water(39g), and Black(39g) water all half full
(figured at 8.34 lbs per gallon) = 508.75 lbs.
Passengers (Three) = 450 lbs.
Miscell = 100 lbs.

2690S - UVW = 11,260.00
343.75
508.75
450.00
+ 100.00

Expected Weight of RV loaded = 12,662.50 lbs.

Then,

22,000.00
- 12,662.50

= 9337.50 - WHAT YOU CAN TOW!

Didn't locate axle ratings yet....?

My trailer, car, golf cart, cabinets, tools, miscell = 8,800-9000 lbs.
