The towing part is easy to explain: Find out what class receiver you have. On a gasser it's propably a class 5, (5Klb)
As for the MH, First thing you have to do is get a 4 corner weight. This tells you how well balanced the MH is to start with. Than look at your chassis identification sticker, located on the wall next to the drivers seat. This will give you the axle weight loading. Now with your 4 corner weights you can figure how much capacity you have over each axle. OK?

JIM: your W-22 chassis is rated to carry "up to" 22,000 pounds on its six tires (GVWR). In addition, you have a GCVWR rating of 26,000 pounds which is the MAX you can safely carry AND tow. Anything over those numbers and you are asking for trouble, either in higher maintanence costs or liability issues if in a collision.

For example, IF your coach, loaded for travel, weighed 21,000 pounds, then therotically you can tow 5,000 pounds and still be within GCVWR, subject to hitch and towbar limitations.

First step is to determine actual coach weight, and individual axle loads are important to make sure you are not too heavy on either of them. Also, this will determine your correct tire pressure and help prevent blowout from underinflation.

Actually, the math part is simple.

Look up the following ratings for your coach:

GVWR - maximum weight of the coach and everything carried by it's wheels.

GCVWR - maximum weight of the coach and anything it is towing.

Hitch rating - maximum weight to be towed by the hitch, regardless of GCVWR

GAWR - maximum weight that can be carried by an axle. Obviously, front & rear axles have different ratings.

Tire load carrying capacity - printed on sidewall of tire & valid only for a tire inflated to maximum pressure.

Next, go weigh your coach. Preferably get the individual weight for each corner because it does vary. Sometimes by a lot.


Now, do the math . . .

GVWR minus actual weight =&gt; maximum amount of weight that can be added to the entire coach IF it was PERFECTLY loaded. If the actual weight exceeds GVWR, then you are overloaded. No further math needed. Put the coach on a diet. Now.

Neither axle should be loaded past their respective GAWR. If the actual weight is less than GVWR, but an axle is overloaded, then shift weight fore or aft as needed.

No tire should every be loaded above it's rating. If the actual weight is less than GVWR, and the axles weights are less than their GAWR's, but a tire is overloaded, then shift weight from side to side as needed.



The toad should never weigh more than GCVWR minus GVWR OR the hitch rating, which ever is less.



FYI: Never load heavy stuff in the very rear of a MH. Try to keep heavy stuff between the axles.

GCVWR minus vehicle weight equals the max. weight you can tow including tow dolly or tow bar.

Sort of wondering if I attach three receivers in the rear of the coach, place a 500lb mc on a rail attached to the receivers, and then run a stinger out to the toad to be pulled. Weight wise it seems less and you have all the toys there with a lighter toad. Would I need to offset the bike weight up front?

I'd feel a lot better with the toad hooked up normally and the BMW slung off the back of the toad.

It's very easy to overload the rear axle with these types of MC carriers.

Blue Ox has a weight calculator HERE.
