The same systems that are in an RV. You have the LP system, the fresh water system and the grey water system as well as the lighting needed to work in the area. These systems are the same systems found on an RV and they mostly use the same hardware. We can work on all of those systems and we can work on the chassis also. If you have a food truck and you need repair work done on it, we can do it here locally in Denton.
