It seems that Thor has come out with a manual to help you calculate the towing capacity of you motorhome.

Thor manual

My favorite parts are:

"To get your towing capacity, it is simply:
GCWR – GVW."

And

"When it comes to hitches, DO NOT USE a weight-distributing or load leveling hitch with your motorhome. It is not capable of transferring any useful amount of weight from the rear axle to the front axle or limiting up and down hitch movement, and you could end up damaging the hitch, the receiver, the rear overhang of the motorhome frame, or the trailer frame itself."

I find these two items fascinating since my several year old Thor coach was advertised to tow 10,000lbs. The first formula gives me 4,000lbs while the second one reduces the hitch capacity to 5,000lbs. I just check and Thor still advertises that the coach comes with a 10,000lb hitch but in my case that is only if you use a weight distributing hitch.

This is a good case of "Buyer Beware!"

I wonder how many coaches actually have a hitch rated for 10,000lbs weight carrying. I want to start checking them out as I see them.

You can check out the ratings here:

Thor Palazzo specs

The Thor marketing group needs to read this manual but since they won't the customers need to.

unless Thor coaches are somehow magical determining the true amount of weight a MH can safely tow requires a bit more work. the basic issue is that it is possible to exceed the GAWR (gross axle weight rating on one axle (usually the rear) and still be under the GVWR.

I believe it comes to what Lawyers tell them what less chances of being sued.

Very astute to lower the max tow weight. Easier to prove an RVer was overloaded when sued...not Thor’s fault.

I had a truck with a 10,000# hitch because it happened to be on sale. I knew the truck was not rated to to 10K but it saved me money. Do the math and be safe.

Except that in the brochure they promote the 10k hitch rating as being the rating for the coach with the following statement:

"The I-Beam front axle with a 55-degree wheel cut upfront paired with V-ride technology helps with stability and handling, even when you put the 10,000-lb hitch to work on your journey to the Unique Museums of the Southeast."

Between that and the specs simply listing the hitch as being a 10k hitch with no qualifications it is very easy to be fooled into thinking that the coach is rated for 10k. Since there own not very well published tow manual clearly contradicts what the promotional literature says the lawyers could have a field day if a case were to go to court.
