How Long is too long
Looking at upgrading. Is a 31' (5220/7230) too long for a Chevy Suburban 1500 to tow. Thanks

Wheelbase to trailer length ratio rule of thumb......per iirc RV Consumer group...
Min WB for towing anything is 110". Maximum trailer length is 20'. For each additional 3 or 4", you get another foot.
With this in mind, this is was for a typical car half ton truck in 70s. Realistically, this will still work for rigs with manufacture gvwr under 6000-7000 lbs, with a typical 5' of rear overhang.
From my standpoint and $.02 opinion.....
If you have a heavier chassis, you can add 3' or so per DOT truck classification you are heavier than a class 1 or ld2. An 8 lug 2, IE what most call a 25 or 3/4 ton to 10k, add 3', a class 3, 35 or 1 ton, 10,000-13500 giver, add 6' to ratio.
If rear over hang is less than 5', to centered over RA, IE 5w, or gooseneck, you can add another 3-6' or so. If longer, like a 15 passenger Ford van, with a long 7-8,' overhang, shorten a bit.
Likewise, the minimum WB of 110"....give me a freaked break! I know of a former moderator that towed a trailer with his Honda Goldwing! So subtract a foot per 3" below the 110" WB!
Again, this is a rule of thumb, a guideline etc. Use at your discretion! Or not!
