Looks like 7200 lbs is the standard GVWR - so the NHT might not raise it any?

Not really a diehard GM fan - Honestly I don't think it matters anymore as they all use the same parts from the same vendors with the same engineers.. All are good and have pro's/con's - so I buy for looks/features/price/capability.. I admit the Ford makes the most sense but I have some personal resentment towards them due to some previous issues (not fitting for discussion here - I'm sure I would get flamed) that I just can't overcome..
