The last 3 trucks that I brought home were all done so on low-boy tractor/trailer combos. Yes, it cost more than a few dollars, but, sure enough, each one of them had concerns that surfaced once it was home. As these trucks get "newer" there is a lot more on them that can "go wrong".
Bottom line - if it is a truck that you want pretty badly, then it is worth getting home in one piece. Additionally, we have to keep in mind the cost of the fuel and our time in the "recovery" process. Let alone temporary plates, temporary insurance, extra this and extra that to be prepared.
Have to be realistic about these trucks. The newest military truck I have is a 1994. Had that one shipped right to the closest (and best referred) truck shop. Luckily, everything important was in very good condition, but EVERY ONE of the hydraulic lines on the material handling crane was dry rotted and had to be replaced (a HUGE pile of lines and $4000.00 later). Now, nothing that would prevent the truck from being driveable, but consider the condition of these lines to be an indication of what CAN happen to much more important systems (think of flexible lines on air brake systems, etc.). And this truck is "only" 17 years old (a baby in surplus military vehicle terms). My F350 daily driver is only 6 years old and I am constantly doing maintenance on it (no Ford jokes here, please - it already hurts). Point is running down to pick up a 1968 Deuce (well over 40 years old!) takes a little more thought than your typical car lot sedan.
Honestly, I have had pretty good luck locating "local" wrecker companies with the suggestions of the GL site reps. One was able to tow a trailer to their yard and store it for a reasonable price while I located a reasonably priced trucking company. That cost was significantly less than the difference that I saved in trucking by doing so.
The wrecker company that was recomended by the Guys in South Carolina for the PLS were great. They were more than familiar with the GL site and the trucks. Had already gotten the other two RUNNING for their new owners (which they also accomplished for me - great comfort, let me tell you). And then when I mentioned that I was looking for a shipper, they offered to load it and truck it themselves for the lowest price I had gotten thus far - can't complain. The less cooks in the kitchen the better in my book.
Just some observations on my end.
Take Care, Dave.
