Length vs weight

First -- the "rule of thumb" does not say a TV with WB less than 110" cannot tow any trailer. It just uses 110" as an arbitrary starting number for the "relationship".

Second -- the "rule of thumb", which frequently is attributed to the RV Consumer Group, says 20' TT for 110" WB, and then add 1' of TT length for each additional 4" of WD -- not 1' for each 3".
IOW, all those people with 130" WB Suburbans should not be towing trailers longer than 25' and a 157" WB pickup should not be towing more than 29' (if you want to believe the "rule").

Third -- AFAIK, nobody has ever produced any data or analysis to substantiate the "rule".

With that rule, I guess I can't tow any more...

Aside from corners in tight urban streets, parking lots and backing into spaces, no. The longer trailer wheelbase tends to track better and be more stable, as does a triple axle. It will probably feel better than your old setup.

Not in my opinion

Reality no.....

altho there is a little rule of thumb some folks follow, goes something to the tune of.....

BUT, I believe this rule of thumb came about back in the days of staion wagons, sedans and the rare half ton truck pulling trailers..... with the more prevalent addition of heavier suspension trucks, longer body styles etc.... I personally am not sure this works completely, but it is a rule of thumb one can follow.......

THen again, the rule of thumb I was told to follow way back when I personally learned to tow in the late 70's, before GCWR ratings existed, max trailer wt was two times the rear axel rating of the tow rig......works well for me. As I find when I start hitting the 2.25-2.5 range, the tail wags the dog more than the dog wagging the tail!

Follow above rules as you see fit!
