Now, I understand that there are people that claim they have moved from a Tahoe to a 1/2 ton Suburban and there was a night and day improvement in towing. This was either perceived because they thought the longer wheelbase would help and just thought it did or there is some other function going on between the two vehicles. If someone has a enough $$$ laying around for me to buy a couple different versions of Tahoes and Suburbans I would love to do a controlled study with scientific data to answer the question
It is not 'perceived'.
That extra few inches of wheelbase DOES make a difference. Can it tow anything yes is it exhausting having to be 'on' all the time driving it x2 yes.
I see you tow with a van. I towed my horse trailers with a van. IMHO it is one of THE best tow vehicles and do wonder why more RV'ers don't use them.
Because you've been spoiled with the long wheelbase and handling of the van, you would pull off the road in 5 miles if you were to use a Tahoe!!!!
Since you have never tried it yet feel you know it doesn't make a difference....I will ship my Tahoe out to you and let you hook up a TT to it and take a trip with it. You don't even need high winds to be disappointed with it's ability. You will be exhausted within minutes being 'on' all the time driving towing with it. :W:W
