I admit that I did steal it
Prices around here are pretty high for running trucks as well. This one may seem in decent shape but trust me the body is really rough. I should take a picture of the left floorboard.... or what is left of it. Still, 1 tons this old are not easy to come by around here so I jumped at the chance to get it.
As for mice, those buggers can get in through very small holes. They can flatten their bodies out so it's pretty easy for them to get into vehicles. It doesn't take much.
