The Progressive Dynamics model PD4635 or model PD4645 power converters are available for less than $200 U.S.
I have not installed a shower however in this thread:
owner discusses what was done to convert the dry bathroom to a wet bathroom.
I have a problem with the exterior finish of my Oxygen. The clear coat is flaking off and the rain water is getting under the clear coat and aggravating the problem by pealing more clear coat. Two weeks ago I took our trailer to a marine/fiberglass restoration shop. I spoke to a fiberglass guy with 30 years experience. He was very impressed with the trailer and said, "I know why they went out of business. They built them too good!" He said the structure of the trailer is extremely sound. There's absolutely no sign of fiberglass problems. He went on to say that what we are seeing on the outside of the trailer is not gelcoat. There is a top layer of clear coat, then paint
(white), then primer (muddy yellow), and then the gelcoat under the primer. Gelcoat will not retain its high gloss shine for 13 years. He sanded a small area to demonstrate all the layers. I can send a photograph if you are curious. The clear coat gives the trailer that glossy look. He said the reason the clear coat is lifting off is probably due to how they painted the trailer originally. He guessed that the paint
was done on a Friday afternoon and the clear coat the following week after the paint
had a chance to cure. Applying the clear coat after the paint cures will not promote a chemical bond between the layers. 13 years later, I find out what they did wrong. He went on to suggest that it's a shame to have to strip the whole trailer down to the gelcoat and repaint but he couldn't see too many other options. The clear coat will continue to peel and must be removed.
Needless to say this will be very expensive to correct, however my wife and I feel it needs to be done. I have read that some of the early models of Oxygens had some quality issues. This contributed to the eventual bankruptcy of Bonair. I think I've discovered one of the quality issues with my paint.
While restoring my trailer I found a factory sticker placed in the storage area under the front seats on the counter-top side of the trailer just to the right of the power converter. It was an old brown piece of paper that appeared to be something applied at the factory to identify the trailer during original construction. Handwritten on the paper is the number 13. Therefore, I've assumed that we have trailer number 13 off the production line.
So you may be reading this and think, that doesn't sound good. It doesn't necessarily mean that your Oxygen has the same problem. The problem may be unique to my lucky number 13. My advise is provided there is no significant surface damage to your paint and tapping on the fiberglass all over produces a solid knocking sound and not a squishy sound, I think you're best leaving the finish the way it is for as long as possible. No need to spend the extra money if it isn't required.
Part of our renovations included all new foam cushions. The original cushions for the back bed were 3" thick (I think) We upgraded this to 4" thick. The original owners suggested this as the number 1 upgrade. All other cushions we left at the original thickness. All fabric is Sunbrella. It's a nice quality fabric that should age well. We copied our interior decorating ideas from another Oxygen owner!
The counter top is a cherry butcher block that I cut using the original counter top as a template. I extended the counter top by 6 inches to the left of the sink to give us some space to place dirty dishes. (Do not under-estimate this upgrade! The extra counter space is very helpful.) I used Polymerized Tung Oil (from Lee Valley) to finish the counter. I'm happy with the results.
I have all the original brochures for the trailer. Thanks for the offer.
If you have any more questions, I'm happy to answer.
Cheers from Niagara.
