OK, here is a photo of the tool I made for the "hidden" nut. It's 19mm or 3/4" and takes a 1/2" drive. I use a several extensions to get up to it but then it's a snap. Squirt favorite liquid wrench a day or at least a few minutes before. I can't remember why I put a little angle on it.

We cut holes on back wall of step and streetside front compartment wall to access these difficult to access holes. We documented with photos. Easy to patch up hole with larger plate. Also gives us future access to the area.

On some coaches, the 'salesman' switch big cables are in the same area, making it an impossible job. We also removed the salesman switch and those two large battery cables.

I do not like holes of any kind so I try to never drill holes.. vhb tape for almost everything.. coach is to nice to chop up.. port holes only look good on boats and lighthouses

I like that idea! Pretty easy to make a cover that will blend in. Will our roof solar, I drilled and screwed everything. I just put a little sealer on each screw threads and call it a day.

As you may know, I rarely say anything positive about the guys at World Line Motors.  But they did have a fast way of removing the air line fittings on the airbags where they are difficult to access (e.g. the forward front airbags).  First, they removed the bottom airbag nuts.  Then they cut the old bags in half (horizontally) and then removed the top half.  They then used an air driven chisel to cut the bottom of the fitting off (the part of the fitting that was inside the bag.  This makes it easy to get out and install a new one.  Of course, it is still a hassle to get the new fitting on.  Removal of the docking lights in front provides a path to the fitting on those bags.  See the pics.

It's nice to see somebody else shares my feelings about drilling holes.  I never understood why people drill holes in everything...especially boats and RVs.  Holes are a path for leaks!  And why ruin beautiful oak or walnut cabinetry with holes?

We used a grinder and basically the same thing but after the first one... We had to brain storm.. cut bag in half is the easiest to start with.. They made a tool that I will have to look at tomorrow to see what it is.. but another idea we came up with is to notch the plate at the big hole or slot it.. that way we can put the fitting on and slip through the slot.. line up the bolts and tighten .. Putting the fitting on on the backside of the rail is difficult so we will talk it over tomorrow.. slot Idea sounds pretty good.

Once the coach is jacked up and secure, if you have a tool to loosen the four hidden nuts on four bags out of eight, the R&R can't be over 15 minutes, less on the bags without the hidden nut. The only thing that slows the process from being faster is the top nuts are fairly close to the rectangular tubing so you can't use a ratcheting box end on them as it hits on the tubing.

We didn't just drill holes, we cut out metal for access. Gave us access to a difficult area. It did make installation easier as we were not going to remove our painted fenders.
