Although my TV has 4 doors, it's not a Crew Cab (Dodge calls it a Quad Cab and its really an extended cab but with forward opening doors) but that's what I voted for it.
I voted for Full-Size 4-door Pickup (F-150 SuperCrew); however, we also use our Full-Size SUV (Expedition).
It really comes down to how many people are riding and how far. We have 3 children; so, we can all fit comfortably in the F-150. But, we often have other children with us; so, we need the extra room of the Expedition.
My F-150 is newer (2006) and has the 5.4L engine which tows a bit better. The Expedition is a 2000 and only has the 4.6L. I have only used the Expedition for short, local trips (within about 1 hr) so far.
Just got a new TV: '07 Pontiac Torrent (same as Equinox). Really like it. Small enough to get decent gas mileage on everyday driving, big enough to haul the fam + mutts, tow capacity well above what's needed for our modest PUP.
1999 GMC Yukon 4X4, kinda heavy but with a 2" lift can keep up with most of the jeeps. And plenty o storage too. Here's a pic at Boundry cone near Oatman, AZ. The top of Mill creek railway trail. 4 hrs to go 14 miles.
Might as well answer up front the "who?" on the 1 person (so far) that answered coupe or sedan (2 or 4 door cars). That would be me, and yes I'm well under my TV towing limits with my PUP (@400lbs/limit 1000lbs) - and I get 30+mpg when towing, even with bicycles on the back (of the car)
I see numerous post on this forum"Will my TV tow this camper?"For years I made the same mistake most make, buy camper then think,"Is my tow vehicle up to snuff".This last time I searched for the vehicle I wanted equipped with a towing package instead of purchase the vehicle then add hitch,transmission cooler etc.I learned that a vehicle equipped with a towing package consists of more than a hitch and cooler.I don't buy new vehicles so I researched and found that I could determine the rear end gear by reading the code on the door sticker and was able to find the vehicle I wanted after several months of looking.I purchased a vehicle rated to tow 7200 lbs so as not to worry whether I was too close to max.A small V8 opposed to the V6 even though the V6 would have towed my 3000# pup.I find that I actually get better gas mileage towing than people with the same setup towing with a V6.I tow in the mountains and the coast with no problem.I just ran a trip without towing and I get 20.5 mpg even with the small V8 only a loss of 1-2 mpg over the V6 same model.Making a short story long if you are going to tow purchase a vehicle built to easily tow the weight you want to tow.The vehicle will last longer and you will have less worry when towing.
