Phantom, we're keeping it simple by just parking the 30 footer on the lake
I had the joy of digging the 6 ft hole for the blackwater holding tank last weekend.
G20, still waiting for the Ikea kitchen bits to arrive but I figure once here we'll be jumping into that project.
Matias, I'll grab a few pics this weekend

The warm weather has taken my activity level way up. See below...
Nich, aside from some lighting automation and a tech "nook" the kitchen area will be pretty simple
One of the first tasks as the warm weather approaches was to resurrect the salt water pool and add some BTUs to the solar heating system. I spent a few evenings harnessed off on our 2nd story roof to add the two extra solar collectors I found used for $100 last fall.
Here's the 2020 update on the system:
1. I've added 2 more 2'x20' solar collectors (last night) for a total of 320 sq/ft. That's about 80 square feet more than the pool surface area. Why? We're close to Lake Superior so our yard can be 10 degrees C cooler than 10 miles inland. Also the pool is shaded so does not get a lot of direct sun.
2. All equipment is now hidden and plumbed into a small Keeter composite shed. This way I can just drain and leave the equipment in place for winter.
3. I now use the Intex pump (SF80110-1)
in series with an inexpensive 2 speed pump (on low speed) which pumps 2 stories up and gets us about 1500 GPH at the pool outlet on solar heat. The combination uses about 5.4 amps.
4. My little solar/rechargeable battery hack worked 100% all the way through winter so I did not replace any expensive lithium cells on the wireless temperature sensors. This "hack" uses three AA rechargeable cells connected to a cheap amazon solar panel (5.0V). The three fibaro door sensors have the lithium cells removed and are directly wired to the AA battery back. These sensors change temps often, so will churn through the expensive lithium cells in 1-2 months. The sensors have not required any power, even idling through the winter at -35C low temps!. The sensors reported low battery at 1% all winter, but stayed running, and continue to run off their solar/cell system.
I'll post results of our first day with 8 collectors! It's going to be a sunny warm day so we should break some solar pool heating records today.
Yesterday saw an 8.6 F degree rise in the pool water (7000 gallons) to about 74 F. This means the system generated 501 466 BTU over the day...not bad considering the max air temp at the pool was 77 F at around 3:30pm.
This is a snapshot of the data around 3:30pm:
Today, it's another cool, partly cloudy day with air temps under 70 F, but it's looking like the pool water will reach 80 to 82 F.
