Yes, it will have good airflow. I do like the looks of it. I just didn't see hiding it in a closet somewhere.
 
Building the shelves that go along the ceiling towards the back. They will be open shelves with dual bungee type strap. I built similar in my 6x12.

This is how they are in my 6x12.

Upper cabinets are in. The front is painted. I'll start flooring tomorrow, then build the couch and elevator bed after that.

Been moving slower this week. I've been doing some electrical work and trim. I just have the bed and couch build, and solar panels to complete. Will start on that after next week since I am out of town next week

On a side note, the AC rocks and the Victron equipment is working great.

Ive got the OutEquip installed on the van and I'm happy with it. I have a post about it on the Transit forum and so far have heard nothing but good things from other people that have installed one.
👍👍

That is good to hear. I really like mine so far. It seems to cool my 8x20 well. I just hope it stands the test of time.
 
Been busy getting some wiring done and cleaned up, installing the stereo , speakers, and getting more trim up. Been sidelined on the build last week while I was away, but should get couch built and the elevator bed started this week.

Those pressure tanks make a big difference in how smooth the faucet runs. I told a plumbing designer I didn't think I needed one as nobody seems to use them in RVs. He gave me the "are you crazy?" look so I put one in and it really helps.

I still need to add a front panel, paint and trim, but the couch/spare bed is almost done. Need throw pillows for the couch, but it is comfortable with the futton mattress.

I'll be starting on the queen sized elevator bed next week. This couch bed will also be used when traveling with the Harley on board since I won't be able to lower the bed with the Harley inside and don't want to have to remove it while on the road to sleep.

Okay, I did get some trim on the couch today and the swing tables installed. I still need to do the top for the other table. I'll get that tomorrow.

I got the window cased. Figured I could square up the trim and paint the rounded parts to match the widow frame. I think it turned out good..I'll have curtains soon.

I still have to insulate and cover the right wheel well. I plan to leave room on the top of the cover for a duct to hook up the diesel heater to. The heater will be a project before winter.

I am starting to design/build the self lifting Queen size elevator bed for the rear of the toy hauler. I am using just one sheet of 3/4 in plywood for the platform structure and an electric motor and shaft for a dump truck load tarp cover. I think the slats when glued and screwed on to support the mattress will tie it together firmly. Just need to get the motor shaft and the roller arm mated and cut down to fit. Once it is fitted and working inside the trailer, I'll trim it out and figure out where to latch it in up position.

I was going to weld up a steel structure, but the cost of the raw material now is crazy expensive. Aside from that, I really want to see how this is going to work for me and if it works well, then no need to change.

The platform is 5 inches thick and I'll have a 6 inch mattress, so with the 7 ft. Ceiling, I should be able to walk under it.

Got the shafts connected to the motor. Next to dry run in the camper before I put slats and trim on

It works! So excited this bed lift works quietly and near perfectly. Now I can add the remainder of the slats, wire it up with a switch and put the lights in underneath. The mattress will be here this week and that should wrap it up for the bed. Only other major work remaining is to mount the three 420W solar panels on the roof, insulate and and paint the Rhino Liner on the ramp , install the Harley mount and then a lot of little things like trim, final paint and stuff like that. Almost there.
