I would also like to see this. I'd like to be able to leave a camper at locations to use as a spawn point. I've left my camper at GE on US-Scourge last night, and logged in the next day to find it 2 squares away and badly damaged. I repaired it and put it back close to GE again, logged off and took a nap, came back a few hours later and it had been pushed another square away and badly damaged again, this time to the point where the lock was gone. I had an admin look into it. Nothing could be found in the logs on the vehicle or it's storage, but nothing was stolen anyways.. I guess somebody has been pushing it around with another vehicle.
Tonight I think I'll try to keep a lookout on it. I've repaired it, put an armored cab on it, and wedged it into a spot I'm hoping it should be pretty difficult for it to get pushed around at least.
I was advised to keep it inside a base and on a lift, but then that defeats the purpose of having the camper in the first place. Or use a sedan, which can't be damaged. I have one, but I can't use that as a spawn point, or extra storage. Maybe if the sedans had beds in the back seat, and storage in the trunk. Is that even possible with a server mod?
I suppose if it gets destroyed by a rocket or something, then it's no loss to me, because if I can't use it as a remote spawn point at monuments, then I have no other real use for it. I don't need it for transport since I have the sedan, and I'm a pretty good copter pilot too. I only have the sedan as a flex I guess.
