Personally i would not be concerned with those pictures. The H2s are very capable of doing those types of obstacles with little effort. Now if he continously beat up the thing thats another story. That being said, the miles are low. For peace in mind you can get an idea of what he has done with the truck buy looking under it. Look at the lowest lying points including the frame and rock rails and see waht kind of damage they have. If he has really wheeled it, trust me it WILL show. That being said, after only a few wheeling trips my truck looks beat to hell underneath. Granted i was on tough trails, by no means has my truck been abused.
You have to keep in mind the cost of removing those rediculous looking light on the side, the tanning bulbs on the front and the silly looking pimp grill
