There is no welding required to install the original Reico-Titan Ground Control system. The mounts for the rear jacks require drilling holes for the mounting bolts. It came with self-tapping bolts, but I preferred to use bolts with nuts. So besides a drill you'll need a socket wrench set and some box wrenches. The front jacks do not required any drilling. The one caveat to this may be any design changes made by Heartland to the front compartment. In mine, the front jacks were easily accessed. All said, it's not that difficult a job for the average DIY'er.
