Disconnect the coach from shore power. Keep the ground connection for the welder as CLOSE as possible to the area to be welded.
Make sure that there are no wiring harnesses, fuel lines, propane lines, air lines, near the area to be welded.
Some people may recommend disconnecting the batteries, or ECM/TCM but I never found that necessary on any of my coaches.
I will second this post and make the very same recommendations.
In fact, when I had to do some welding on this rig,,,,,that is exactly what we did.
One other POSSIBLE solution ... I have had this rig welded upon twice, The second time they welded OFF the Rig.. that is the parts needing welding were removed (They bolted on) and the work was done on the bench in the shop, and then bolted back on the Rig.
Battery trays may be doable that way.. Depends on the RV.
