Good luck with the renovations. We renovated a 1989 Captain
N126 and it turned out well. The captain
is now with a new owner as we decided we wanted a bathroom.
We replaced the vinyl floor (including one corner of the plywood) and the knitted polyester liner but kept the original curtains and cushions and covers. We also replaced the vinyl strip on the exterior aluminum channels. We had to buy it in UK because they don't sell the right size here. After an incident with a garage door, we had to replace the roof hatch. We got a new one shipped from Poland. Trim is gray, not brown but who is looking. .......
The stove top and sink are the original ones. The little submersible pump still worked so nothing changed for the plumbing. We had the original add-a- room complete with all the crazy aluminum pipes. We also re-installed the surge brake system that a previous owner removed and stored. We never had the hammocks that went over the dinette.
We added some electrical
outlets and a TV mounting bracket and an aluminum Venetian blind over the stove (for safety - we didn't like a cloth curtain over a stove).
We pulled out windows
and resealed them with butyl caulking. We used the same rubber gaskets and windows
One thing I wish we had done when the liner was ripped out was to replace the screws under the exterior aluminum channels with stainless steel ones. The old screws were rusting out and turned out to be a source of minor leaks
If I was feeling rich, I would have painted it. That's for the current owner😁
