My best advice would be to borrow/rent a truck and trailer. That way you don't have to worry about registration/insurance hassles, and I've known more than a few people who bought a used car and immediately turned around and made a long trip, only to have to deal with a breakdown or other issue. I'd be real leery of depending on an old truck with unknown history for a long drive without taking the time to shake it down beforehand.
X2....sometimes a trailer,tow or ramp truck is well worth whatever it costs....one thing though,borrowing a truck,trailer,or a ramp truck can also bring problems ,you dont really know what condition they are in,and they can break down too!...though it is costly,paying a legit hauler is probably best,then if they have a breakdown its THEIR problem..
They are insured too--your truck probably wont be if its on a borrowed trailer and something bad happened to it..
I've had my share of harrowing rides home from a vehicle purchase--nothing like "trusting" a truck you drove only a couple of miles around the block to get you 100+ miles home,and finding out it has tires that are oval as eggs,death wobble at 55+mph,and a few other un-nerving noises and habits that keep your knuckles white and your heart in your throat the whole trip...worse,if it does crap out,your not only broke down,but in an area totally unfamiliar,and you haven't a clue where the nearest service station is,or which one rips off tourists..
One friend of mine bought a ;58 Chevy Impala in CA,and decided to drive it home instead of paying 1000 bucks to have it shipped to MA...
"The tranny leaks a little",the seller said.."Just keep it full and I gaurantee you'll make it no problem"..
Well,"a little" turned out to be a quart every 50-100 miles,and it got worse the farther he drove...he told me he bought 4 cases of ATF and filled the trunk with them,used all 48 quarts before he got to Illinois,where he bought another 4 cases!...he had 3 quarts left when he finally pulled into his driveway--but it made it!..he sais he got pulled over in OK and Illinois for "excessive smoke" when the ATF was burning off the y-pipe,and the cops almost made him have it towed to a shop too..
It sucks the "perfect" truck always seems to be on the other side of the country when we finally find just what we're looking for--rust free,low miles,a particular drive train,lower price than anything local if it even existed,etc...just like every time I find something I want on craigslist,its always at least a hundred miles away..especially if its in the free listings..

lol, drive home.
I could give it a quick look over if you want to save you a trip to find if it turns out to be a POS...
