understanding GCWR-GVWR=TOWING?

GVWR 22000
GCWR 26000

Does this mean towing capacity 4000 lbs?

If Dry weight + cargo < 22000, does this mean you can tow more than 4000 lbs?

Hitch Weight Rating: 8000 lbs. Does this mean you can tow 8000 lbs behind it?

Are both of those from the tow vehicle? They don't seem right to me...

Yes, if the MH fully loaded is only 21,000 you can tow 5,000, but just because you have an 8,000 lb hitch doesn't mean you can tow 8,000 unless loaded you only scale at 18,000.

Thanks.
Hitch weight rating is max tow weight. Where is the vertical hitch weight in the picture? In weight scale, how to know it does not exceed vertical hitch weight(e.g. 500 lbs)? Thanks.

Ahh, that makes sense. I wasn't thinking a motorhome... I'm such a TT guy

You go to a truck scale. Weigh the Motor home with the trailer attached then weigh it without the trailer, or vice-versa . The scales have multiple sections to do just that. A 8,000 lb hitch probably has a 750 lb tongue rating.

The hitches installed by Thor are normally 8K hitch with 500 lb tongue weight.

Yes, the hitches are overrated for the towing capacity on some of the Thor motorhomes. Thor made a change to the hitches in late 2014 or early 2015 when Lippert (LCI) quit making the 5000 pound hitch. Same thing occurred at the same time with Forest River and their class c motorhomes. My 2015 Challenger which was built in Aug of 2014, was one of the first Thor's to come out of the plant with the 8000 pound hitch and only having 4,000 lbs of towing capacity.

I see. but it takes time to unhitch and then hitch in the truck scale, especially other RVs waiting behind.

How dangerous driving on road loaded more than any of the weight ratings before reaching truck scale? throw away stuff if overweight? Any way to know RV weight before starting journey? thanks.

Is it dangerous to rate hitch as 8000 lbs which actually is 4000 lbs?

The hitch is rated and is actually a 8000 lb hitch. The motorhome only has the capacity to tow 4000 lbs. Don't confuse the hitch rating with the vehicles towing capacity, they are 2 different animals.

The thing that is dangerous is the operator that doesn't know what they are doing , or understand their rig's towing capacity, and decide to run down the road a couple thousand over.

If the GVW is maxed out at 22,000, but if that is 1,000 below the rating you can tow 5,000.

A CAT scale is your friend.
