Help in choosing tow vehicle needed

I call it the ability of the TV to 'manhandle' the setup during adverse conditions
AKA that emergency situation when you have to manhandle the setup

Note that in addition to needing trailer brakes above a certain trailer weight (that
weight limit is different from state to state), but that around that weight...the
trailer tongue becomes both an issue with the TV's rear axle weight rating and
the biggie: the TV's receiver rating requires a WD Hitch system

Read up on the potential TV's design and whether the OEM allows a WD Hitch
system or not. Mainly unibody/monocoque designs.

Gather these ratings for the prospective TV and use them to compare

GVWR
RGAWR
FGAWR
GCWR

Then the simple math to figure the range...

GCWR >= TV + TT + hitch weights (equal to, or greater than)

If you don't have their actual weights, then use their GVWR's, which is the
heaviest they are rated for. Of course if you will NOT be loading them up to
their GVWR's, then you have more fudge room for the 'other' (TV or TT)
