A highly experienced RVer documents the step-by-step build of a custom 8x20 Diamond Cargo toy hauler, designed for off-grid comfort and to accommodate a Harley Davidson Ultra Limited. The project features a robust electrical system with 640Ah LiFePO4 batteries, Victron Energy management, 600W solar, and a 24VDC setup to support high-efficiency rooftop AC. The build also includes large water tanks, on-demand hot water, induction cooking, advanced monitoring, and four-season insulation...

Got the slats and etc. on. The bed lift works great and looks good for DIY.

With the mattress on, the bed pulls up tight to the ceiling which will stop any swinging on the straps when traveling. I will also be putting some pins in each corner that will go into the wall and allow me to take tension and strain of the belt system when traveling. I just don't want there to be any chance of the bed accidentally dropping onto my Harley. That would be a bad day.

Thanks Bruce. This basic design has been out there for a while. I just had to figure out the dimensions for my situation and make the decisions on materiel to use. Alot of folks use extruded aluminum to make the frame, but that was more than I cared to spend on just the frame, so I decided to go with the plywood and given the extra weight, I bought a stronger motor. I am also adding in limit switches into the control so that it can't overtdrive in either direction and start breaking things. Nobody seems to mention that.
 
Working on the ramp today. I welded in cross member to support the spare tire rack I am mounting on the ramp outside. Also painted the metal and insulated. The wood is drying now. I used a Herculiner Truck Bed anti slip paint. It is going to take 24 hours to cure then I will put it all back together.

Wrapping up this build in the next few days. I need to install solar panels, the motorcycle mount and then some misc. paint touch up and trim. Glad to be wrapping it up. I'd rather use it.

I actually got two of the three 410W panels on the roof before the rain today. I'll get the third panel and the wiring done tomorrow if all goes well.

Moved the new CTC to the backyard. All done except the Harley Mount which I'll install this weekend. Have some trees being cut down out front, so had to get it out of the driveway.

I finished the build last week, but this is the first time I've put the Harley in. It fits well.

Also running the AC straight off the solar panels. Solar powered AC... Love it!

Beautiful trailer! Keep us up to date on all of your travels in the new rig. Now I just need to get back to my build as soon as these temps drop below 100 o_O
 
Outstanding work Mr. Smith! What a beautiful rig. I just got in on the last few pages here so I will have to go back and review the entire build, but this is impressive. And in record time it would seem. Congratulations my friend.
McDave

ps. Sweet Scoot, too. They are just so cool, ya know?
 
Thanks McDave. Always good to hear from you. I sold the 7*18 Vnose last June because the Harley I bought would not fit. Did Route 66 with the wife last September and she loves the Ultra Limited, so I am keeping it and built this 8*20 out to hold it while we travel. My wife finally retired and will be traveling more with me now, so this should be very comfortable for us and the Harley.

I'll be at Sturgis this year. Parking the CTC in the driveway of an Airbnb my brother is renting with some friends. Not in Sturgis proper, but somewhere between there and Rapid City. In any case, the maiden voyage of this build starts July 28.

Keep in touch. Best wishes.
