I carry a small 4 drawer tool box with the usual mechanic hand tools including a torque wrench. I also carry a cordless drill and driver some drill bits and about ten pounds of various nuts bolts and screws. Also gorilla tape, gorilla glue, wire ties silicone and wd 40 spray. My present coach has a rubber roof so I carry a roll of repair tape and quick dry silicone sealant. I have used it more then once for when those low hanging branches strike. The one thing I don't leave home without is my Good Sams Road Asst. I have used them twice for blowouts, once for a lockout and even once to change the flat on my TV.
