Length vs weight

We are selling our current trailer and buying a new one. On paper the new one has a gvwr 1000 greater than our current rig and a dry weight about 500 lbs greater. In the end we will end up with a 500 lbs heavier rig ready to roll down the road.

New trailer is a triple axle.

New trailer is 7' longer.

Truck is rated to handle the weight; should there be any concern about the length?

Reality no.....

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

MIN WB for ANY trailer is 110" ie up to 20'
Then you need 3" of WB per 1 additional foot of trailer length

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!
