hey, i need a good truck for maneuvering in mountains as well as towing a trailer. do you think that this 2500 HD Crew Cab in 4WD (you can see it here:http://www.chevyworktrucks.com/inve...35105/ID_qualitychevroletfleet/UI_detail_new2) will work? or should i get something with rear-wheel drive for the towing. i also want a crew cab because i need to take my family with sometimes. i'm not really sure if i can get everything i want in one package...what do you guys think?
