Hey!! I am new here and to RVing.. My wife and I are looking into getting a RV... we have been looking at lots of models... TT's 5er's, pushers... we have pretty much decided we are going to get a 5er... now the question.. I am wanting to purchase the RV then match the truck to it... I have been looking at GVWR, GVAR, and the likes.. is there a clear cut way to figure out how much truck will be needed to tow the RV?? right now I have a '99 dodge 2500 2wd ext.cab... I am not opposed to going with a bigger truck... but really confused with the ratings on the trucks and how much tongue weight can be put on the bed...
