I just bought a new 09 Challenger SE and am looking at new trucks I have my work truck 06 Chevy 3500HD Dully dump body extended cab and was looking for more of a family oriented truck I like the new Colorado's but was not sure if the 3.7 straight 5 was enough not to overload the engine I know they are rated for much more then the boat weighs but I will be going on some long hauls with the boat and family, it will be a Crew Cab LTZ loaded with trailering package I know they come in the 5.3 but the reason I wanted the Colorado was for better fuel economy and it will be the wife's in the winter when she doesn't want to drive her front wheel drive 08 Malibu in the snow (We live in Maine). What do you all think.
