Looking at a 2003 Monaco Knight 32' tomorrow.

Not sure what drive train that Monaco has. But my '04 Holiday Rambler had the Cummins ISC330 with 950 ft.lbs. of torque and Allison 3000 Trans. And it was a 34' motor home. Had plenty of ooomph! also 10k towing.

That Allison 3000 is where the towing capacity comes in, along with wheel base and some other factors of course.
Nowadays, with some of the entry level models, they can go as big as 40ft with a 2500 tranny, have a 32K GVWR and thereby being close to max. GCWR, before hitching anything up to it.
There's this mindset out there, that a big DP can tow pretty much anything, but nothing could be further from the truth.
When looking at the initial specs and sometimes leaving out the critical points, it might say that it has a 10K lb hitch receiver, but so what, if there's a weak link somewhere else.
I'm good to go for 15K lbs towing, but with the rear axle, already at max. there's 0 hitch weight left and even though the hitch has a 1500lb rating. We always pull four down, so no problem, but just saying it's a no no for a big enclosed trailer, if you follow the specs. Interesting that we're good with the total weigh ratings though and just that the ton excess, that we have, is all on the front axle.
Not sure what an equalizing hitch would do for one in this case, but again, it's not am issue for us.
