During the last trip, I ran a couple of medium sized buddy heaters in the motel to take the chill out. After running the two for a few hours, I cut them down to low and maintained that all night. Kept the trailer nice and cozy. I'll chalk that up to the tropicool air sealing more than anything, as there's no insulation in the ceiling yet, but I'm stoked.
Have another trip in a few weeks, and have been plugging away at the next phase. Goals are:
1. Plumb the fresh water tank
2. Reinforce the floor where the kitchentte will go (current plywood is cupping a bit)
3. Move the electrical controls into the kitchentte
4. Build the dividing wall
I've been plugging away the past couple of days towards those ends. Pulled up the front two floor pieces, got some bracing in, routed the fill and vent lines for the water tank through to the fill point on the exterior, then routed the tap line into where the kitchentte will go.
Added the angle iron center frame, and shimmed up the storage box with some steel to act as the second support. Floor is plenty rigid now.
The tank came with these "uniseal" things that are pretty neat. There are no glued-on or formed-in threaded connections on this tank at all. The uniseal works by cutting a hole in the tank, pushing the seal in, then pushing the appropriate size PVC through the seal. This forces the seal against the wall of the tank, and it's good to go.
Cut some holes in the crossmembers and routed the lines:
Detail of the tap. Put this ball valve in there with enough slack in the tap line so that I can rotate the ball valve down to the ground and drain the system.
Floor back in with the tap line through the floor into the kitchentte area.
Currently mulling over how to build this dividing wall. I'm inclined to cut away some of the insulated sub-floor and build a steel frame on top of the goose, but I'm not married to that idea. There's not much wood to attach to in the goose area. Open to ideas on how to frame this out. Included will be a cabinet that will hold a fridge and microwave.
Suppose I should update my CAD model to reflect my plan to make it easier to understand.
