Sanky Roof Top Tent Design

Got the tent and rack up on a 110 roof today for the first time.
It takes 4 people to lift it up on a vehicle.
Tent is in really nice shape.

Pictures are just for size reference... we want to mount it on a trailer.

Am thinking about a design to mount it to our Sanky that will include height adjustment.
The most simple is 2 pieces of pipe with pins to position the height.
The overall goal will be to have the tent mounted low for travel and then raised for sleeping and accessing gear stored underneath in the Sanky Trailer.

We are going to use the Front Runner wind Cheetah rack and just have attaching legs.
Looked at the mechanism used to raise and lower pop up campers, but for various reasons, it will not fit and is probably not strong enough.

Any thoughts to collaborate on a telescopic trailer mount design?

Doug you can buy some gas struts - two with 150lbs ea to help you with raising the platform when you need to.

Of course going to Expo portal will get you a dozen opinions on designs.

On that note, Logs are a perfectly acceptable mounting point for anything.

Craig- I like my setup and have no plans of changing it, other than have Tom Slaughter make me up an enclosure. This is Roberts thread so I'm interested to see what he comes up with. Don't be surprised if it involes some Benz parts

I think something like this is your ticket. I can't see the video on my phone but if I recall, this system could allow you do something similar with a RTT on a trailer.

Machinist is having a look in the morning to see what we can come up with.
We are going to explore a cable design on 4 poles similar to what a 4 post lift has.
The whole thing operated by a small electric winch.

There has to be a better way to accomplish this.

Went through my scrap steel pile and located some of the stock used for class 3 receivers and hitches.
Fits nice and won't gall like aluminum or stainless and is cheap.
So will mount 4 of these on the outside corners.
Then the rack will have 4 legs.

The next step is to figure out how to raise and lower the assembly.
I have a hydraulic hand pump from an MG YB built in jackall system that I might be able to use.
There would be a single jack in the middle or one on each side to raise and lower the tent and rack.
Another option could be trailer tongue jacks.
Just brainstorming at this point...

Have you considered converting or replicating parts from a scissor lift?

I think Robert is looking for something mounted on the perimeter that won't interfere with access to gear stored in the bed.

Here is mine in need of a canvass enclosure with roll up sides. I need to cut the corner tips off so the canvas will have a smooth profile.

Understood. Mount the "scissors" on the sides leaving the bed clear.

Try unistruts for the two side rails (available leftover from most jobsites) and mirrored on the tent frame. Pin one leg of the scissor to the unistrut and use track rollers on the leg of the other scissor (many roller options for unistrut). To hold the scissors in the expanded condition, slide a pin through the unistrut in front of the roller. The scissors could be made out of most anything but I'd go with unistrut there as well. Best bang for the buck. Shoot, I could see the Dro having 200' of it stashed someplace.

Not sure what to use to jack up this assembly. Perhaps two bottle jacks mounted to the sides of the bed, but plumbed together.

I would figure the weight Robert then use gas struts - 2 - 1 on each side - that will push the weight up when you unpin them, to the desired height then pin the 4 legs at that height. Mount them on the outside lip of the tub where they won't interfere. If you do it right one person should be able to lift the platform up with the aid of the struts and then one person should be able to pull it back down and secure it without any real effort.

REMEMBER - you want to design it so that you can put all the poles, etc in - basically put the tent up in the down position then raise it up...so you are not on a ladder trying to do this. Like rolling up windows.

Here is another scissor idea. Stage risers. http://s1074.photobucket.com/user/yo...?sort=2&page=1

looks to be a fixed ladder rack for a Ford Ranger type truck...
