Hi. nice to hear from another owner.
The unit I have was built in November of 2000 and the black/grey water tank was essentially a 40" piece of 3" ABS pipe..so no tank. As such the toilet setup was not very functional and a shower out of the question. A plumbing redo as well as a new tank was required. I started looking for something off the self. I wanted the largest tank possible with a maximum height of under 6" to stay level with the bottom of the axle
and a shape which kept the weight
forward as much as possible. Also the outlets needed to be where they would work. The largest tank I could find was 8 gal which from experience is too small for a combined tank. I ended up fabricating one out of fibreglass estimated size of 15" wide X 6" high by 48" long, approx 13 gal. With a combined tank you have to be careful to prevent backflow of sewer water into the shower so the drain has a push/pop up drain plug which is closed any time we move. There is also a p-trap below the shower to prevent odours from coming up the drain..
The tap for the shower is located below the level of the bed so the water lines are hidden in the locker. Hot and cold water lines are plumbed into the existing near the h/w tank and the pump.
I redid the frame only because of surface rust and I wanted to make sure the brakes
were ok and hopefully provide another ten years before the next maintenance work. I also sprayed rustproofing into the frame openings.
I will take some pictures of the bed/table mod over the weekend. There are only two of us so my thoughts were to get rid of the very heavy and awkward table. Reduce the table size and weight
. Add space for a small microwave
, coffee brewer and toaster. Add three small storage compartments. I also wanted to make sure there would still be easy access thru the four access hatches in the seats. The table itself also hinges up and out of the way. When the table is up there is surprisingly more floor space.
By lower cabinets do you mean in the kitchen?
