I would look for a used Mega Cab, may be hard to find since they just started making them in 06, maybe one with a Hemi. the Hemi is a good gas engine, I have driven them and they are pretty powerful. My old boss's 2005 6. 0 PSD was a nightmare for him, overheated all the time, ended up completely blowing the engine while towing his 10K toy hauler, the engine was replaced by Ford, he only had around 30k when they had to practically dismantle the whole truck to replace the Powerstroke. Then when his truck hit about 38K the transmission sprung a leak while he was driving down the road not towing anything, started dumping all the transmission fluid all over the road from a quarter size whole that opened up on the side of the trans, and since he was just out of warranty they told him he was pretty much SOL, and would have to pay to fix the trans. His brother also bought a 2004 6. 0 PSD used from a Ford dealer, a gift for his wife, on the first trip he took it from the dealer where he bought it with 45K on the truck, to pick up his toy hauler and go to Sand Mountain, 50 miles out of Sacramento the lights all went off on the dash and it died. Turns out the engine completely blew, the dealer he just bought it from the same day towed it back and replaced the engine. Ford trucks are nice, I like the room, but the drivetrain is a POS, look under the hood and you will be scared, you can't stick a pencil in there it is soo packed. I am not biased against Ford, but when two people I know have had major engine failure on relatively new trucks, you know something is wrong with the engineering.
