For future reference, will they allow me to hook up batteries, add fresh diesel, attempt to start and drive it back ay forth at Pineville? This was my first rodeo...
Every site is different. You have to ask. As far as pulling it around the parking lot, NO! As far as pulling up 15', back into place, most will if you put the time into starting it.
They don't want any unnecessary liability with people driving around the parking lot having a joy ride, when they have millions of dollars of equipment out there, plus the personal liability.
You can find out a lot with a slave cable and two freshly charged batteries. A visual does little but to rule out the obvious from obvious damages, rust, etc. but you have a long way to go after that, and starting and warming up is key to a good investment. If CTIS didn't pump up the tires in five minutes or so for instance, you know you need to trailer it home. If it does, you still need to inspect after full pumping for cracks and such. On the internal batteries after startup, you need to check the recharging system and make sure it is doing it's job. And after your buy while waiting for the EUC to clear, it would be a good idea to go back and restart to keep the batteries charged and tires pumped with fluids flowing every couple of weeks of so, if you are within driving distance. If not, maybe someone can help if they are in the area.
