Do I 'need' a WB 160"-175" for a 30'TT?

Picking up my new 30' TT at the end of next month. TT UVW is about 5400 and GVWR is 6800lbs. I am going to purchase a 3/4 ton pickup, so I have the extra payload capacity and peace of mind towing with a more powerful TV. So, I went to a few car dealers this weekend looking for a late model pre-owned crew cab.

Now I realize a longer wb will give more towing stability. The wheelbase 'calculator' (that may or may not be bogus anyway) tells me a minimum of 150".

That's pretty much mid 150s" on a reg/short box crew. Long box crew puts me at high 160s to low 170s.

Not opposed to a long box but would there really be much noticeable sway & towing difference with a reg box?

For those that have towed with both would you highly recommend a wb of 169"/172" over a 156"?
  • i tow my 31' Tt with a 145" WB 150. I have no sway at all. Notice. No manufacturer has a length limit on towing based on TV WB.
  • Wheelbase is but one of many factors that can improve towing comfort of very long TTs. With the TT outlined above any late model 3/4 ton truck will handle the load easily regardless of wheelbase, granted a high quality WD/SC hitch should be part of the equation for best results.
  • With the weights of the TT any 3/4 ton, lengths a non issue. My prior TV was an extended cab long bed towing 33ft just under 10K. Your hitch will be more important than the length.
  • Just remember the old regular cab pickups, with 8' bed. They were great TVs, but shorter WB than the crew cab standard bed of today.

  • I sincerely don't think you would ever notice any difference between any of those - towing wise.
    If your not going to ever haul anything long, I would get the shortest.
