I don't know if anyone is interested in my maintenance and mods, since most of you covered this ground several years ago.
I have noticed that several of the complaints from the owners of the earliest units seemed to be addressed in my 05. Which is nice.
Maybe this only applies to the 213, I don't know. Today, while I still have the water heater out awaiting a new tank, I installed a shelf into the space forward of the water heater. (It was much easier to do with the heater out.) There was wasted space there, above the tail end of the wheel well under the kitchen sink. The shelf is 15 x 21, but with two water lines passing through it. There is room for about 6 shoeboxes or large loaves of bread, to give you an idea. Storage space is definitely scarce, so it will be nice to have this available.
I think I will go back and shove some insulation on top of the wheel well under the shelf. Why not.
Directly in front of that space, they had stapled the wiring for the LP detector to the middle of the otherwise open cabinet floor. I pulled it up and used some plastic loop hangers for 1/2" cables to attach the wire harness to the cabinet inside frame instead. Now that floor space is available to safely store things too. There are water lines adjacent to the left, but they are not so delicate that some things can't be judiciously stored next to them. In our trailers, this type of space was never blocked off, instead it was available for use.
Finally I added some wooden support cleats directly beneath the plastic wall hangers for the kitchen drawer slides. I have had those hangers break in our trailer, so I figured now is the time to try to improve these. At least in my 05 they are mounted on boards instead of just the wallboard as in the earlier models. But even with good mounting, those brackets are a weak link. I hope the cleats will provide support to avoid them breaking. Nothing ventured, nothing gained. It was really tough to get in there, though. I used a staple gun and it gave me enough extra extension beyond my reach to just get there.
If anyone wants photos, let me know and I'll post some.
