I began my first project on our new/old RV last night, it is a 1973 Layton TT. I was replacing a brake light on the rear. Since the old one was broken and replacement plastic was not available. I removed the old light and cleaned up the butyl tape as best as i could. Any suggestions for removing the residue? I took the old screws mounting the old light to HD and got new ones. They matched up with 8 x 1" pan head sheet metal screws. I aligned the new light and drilled a hole through one of the mounting holes into the trailer then installed a screw then drilled the other 3 holes. I lined the back of the new light with butyl tape, then sunk all four screw to mount the light.
The problem is the screws did not really catch, they just seem to be spinning like i stripped the holes already. I was using a cordless drill and had the clutch on a low setting. I wanted the screws to bite enough to suck the light up to the trailer to seal the butyl tape, but did not appear to happen. I will try to get some 10x1" screw to see if they will hold better.
Did I use a too big drill bit when pre-drilling, or should I not pre-drill at all?
I would appreciate suggestions on how to use the butyl tape as well. I just put one layer around the perimeter of the light, not sure if this is thick enough to get a good seal, should I put two layer or roll the tape to make a thick layer nearer the edge of the light?
My next project is to mount the converter inside the trailer. There is not enough room where I want to put it to lie down so I will be mounting vertically. It will be in a bench cabinet. I will be putting some wood below to get it off the floor to clear some water pipes running there. I would like to mount the screws into the wall to kind of hold it into place, then add a piece of wood on the backside, so it is wedged into the cabinet and to give it support so the screws are not trying to hold all 30 lbs on their own. What kind of screws should I use to mount things in the interior? What kind of structure is behind the walls to support things or mount into?
