Need help building rooftop hammock stand on Prinsu Rack (1 Viewer)

So Single triangle at the end w/o solar. other end you have a triangle with y-axis (a) that can be disconnected from the C support (you know from a2 + b2 = c2) allowing the y-axis to lay across in front of the solar panel. the x-axis could be permanently fixed and your C support and y axis could use a Ujoint style hinge so they could fold as well as tilt out. as long as you can connect the y-axis and C support well, that will have no play in it.

Most solar panels (not saying yours is one of them) stop producing if there is any of the cells being covered by shade. May consider just making the solar panel removable and mountable over the windshield while parked.... protects your dash.

also... with the straps and hammock handling the tension, the hardware doesn't need to be that strong. as all the pressure would be downforce. the C support one both triangle would handle any side to side. Not suggesting PVC, but you wouldn't need it to be that heavy duty.

There's a lot of potential in that design. I need to see what corner connections are available for the A/C joint at 45 degrees. The panel isn't heavy but a bit unwieldy. I thought about mounting the solar panel over the rear window where it works with the hatch open or off the side over the drivers' window and hinge it up. Still need to think about that.

Something like this would suffice I think: 14011 - Shop

Here's the placement of the solar panel:

The tensahedron idea could work with two up top. Have them set up so you hang perpendicular to the truck. One over your solar panel, one over the platform. Anchor the hold down strap on sliders etc

How do you access the platform?

One thing that strikes me about the tensahedron idea is the simplicity, and elegance of the design.

The load on the poles looks like it's mostly compression along the length of the pole. No hinged joints, no bending/leverage load on the poles. This means you can use a smaller section pole. Also no bracing.
It would break down to a small bundle of poles, and some cordage.

I agree, I really like the simplicity of that design. I'm going to try out a few ideas, see which is the most versatile, cheapest, easiest, etc. I use a telescoping ladder thst can be positioned and locked in anywhere along either side of the truck. I need to research how to build that design; materials, joints, etc. My only concern is that all 250lbs of me will be focused on 2 points, 1 per bar. I can use a scab to spread the load out and also act as a socket or mount point as well. I am nervous about the single tether, wouldn't want to topple off the other side should the tether let go.

Ha ha or a 40MPH wind gust perhaps blows you towards the tether and off the roof you go. I had the same thought as well. It would be awesome to have a versatile solution that could be used on the truck or on the ground though.

Up on the roof I would definitely tether both ends. The "primary" would be as shown in that thread, the "secondary" would be at the other end. I would construct it of webbing and sew a piece of bungie/elastic so that it had some give, but if things got out of balance, it would pull tight in a short distance.

 

[Dissent]

The build thread did note to tether both ends if needed. he built that prototype out of Carbon Fiber but it was destroyed in an accident. He said attempts with aluminum didn't work out, too light. I'm only on page 4 of the 30 something though.

 

[mudgudgeon]

yeah, I think tether both ends is a no brainer.

keen to hear what you come up with.

How about a hitch mounted hammock?

Does it have to be on the roof? This seems much simpler. You could even tarp off the rack. Without bumpers you could go from the pintle hitch and front cross member.

Guess I better jump in here...
Trees? We don't need no stinking trees!
I spent 8 of the 10 nights in my hammock in Baja, it was kick a$$!

On the 80 I had them built into the custom bumpers.
On my 60 I took a small piece of 1.75" DOM and sliced it into my bumpers at roughly a 45* angle then made some poles out of 1.5" DOM that slide in perfectly, works like a charm. I store the poles on the roof rack with some Quick Fist Clamps, Takes about 3 minutes to set up. I also put a 3" foam pad in the bottom of he Hammock on those cooler nights.

I like this idea, as well as the receiver mount one

That is exactly what I was thinking about 2 years go. I love that telescoping setup. On a side note, I can't find any OTC front receivers for this truck. Going to have to have one made.

THIS THIS THIS THIS!!! I've worked with my local fabricator twice trying to do this WITHOUT HD plate bumpers (I'm still OEM). The rear is feasible but the front is a no-go. The frame is like 16" from the tip of the bumper. There's too much weight hanging out there without some support from the top, which there's nothing to anchor to. That said, I may still pursue that setup on the rear but go with the reciever mount mentioned previously or worst case, have something fabbed up like the ENO Roadie which just plants under the front tire with a angled receiver poking out.

If I was doing this off the hitch at the back, I would add 3 ft of square tubing, and a trailer foot to add ground support

 

[satchel]

I like the idea of the hitch mount. I wonder if the gamiviti spare tire receiver would be strong enough? Spare Receivers

 

[Dissent]

That hitch mount is awesome but it's $400 and is limited to 116" hammocks. Mine are 120" and 132". I have an email out to see if the arms can be extended to accommodate the longer hammocks.
