If you want to put threads in a hole in the frame you might want to check out "Rivnut" or it's equivalent in another brand. You drill a hole, put an insert in it and "pull" it like a pop rivet. They have both shouldered and flush models. If you install them right they work pretty good.

I think for what the OP wants to do we are talking about a couple of 1/4"-20 holes. Don't think it's a big deal.

I’d say applying to bare metal is not a requirement, but check the instructions for the particular adhesive. I’ve used it on the fiberglass roof to attach brackets for a solar panel. That thing isn’t coming off without a fight.

As far as the 12V water pump, I believe ours is screwed to the ceiling of the basement storage compartment, aka the sub-floor. Personally, I wouldn’t go to the trouble of drilling into the frame to mount a water pump.

If you want to relocated stuff to your battery bay, another option would be to use industrial adhesive to mount a 3/4" thick sheet of pvc board to the frame rail, and then use that to screw your water pump and other stuff to. Would be much easier in the future if you have to move things around a bit as well. You could also use some plywood if the bay is dry as the backing board. Lots of good options for adhesive that will hold the board in place.

there are devices called "BEAM CLAMPS". They are small C shaped heavy duty devices used for HVAC and plumbing in new buildings. They attach hangers to the structural members in new buildings so workers don't have to spend time drilling holes. They look like a small "C" clamp complete with a tightening screw. they also include a pre-drilled threaded hole for a 1/4" bolt or whatever. you can probably find them in most good hdw. stores, or definitely a plumbing supply store.

I think a clean de-greased surface on the RV frame would hold a good adhesive with no problems.

I'm not understanding how you would attach these to a tubular frame.

Tubular frame rails?

Alpine rail is not a tube.
See image attached.

Right now, my water pump, battery boost and some other stuff is factory drilled and mounted to the frame. I just want to add a couple of busbars.

From the photo it seems like there's room on the two sides of the bay to add what you're talking about, and you could easily drill there without any worry about frame damage since those are not the frame rails.

For mounting directly to the frame rail side, if there are existing items mounted couldn't you just fabricate a metal bracket for them which is mounted by sandwiching the end/edge of the bracket behind the existing items using existing mounting hardware?

I am considering that option richard. On my Alpine there is an existing unused hole on the right and existing holes on the left from the boost relay.

So, I could securely attach a thick plastic board and mount things to the board.
