a simple hardside popup

Here is the latest of my small, folding trailer ideas. This one tosses out the hope of a nice shape in favor of a simple design. Again very similar to an Esterel, but only one end lifts. With the rear part of the roof having a drop, needed height is acheived without lifting so high, and the rear wall can be straight up. The level body top makes the folding walls easy to operate. Yes, a slight curve could be addd to the roof for drainage; it's flat for easier proof-of-concept drawing. The roof fits over the body, sealing it well while both closed and open. Roof is hinged from inside, ensuring weathertight operation.

The body sidewalls are 4' high. Interior height at apex is 7.5'. This version has a 9' long body. I also have a 12' body drawn, but prefer the shorter one for off-road-ability. The added interior length is very tempting, though...

LOVE it! I wonder how light it would possible to make the roof.


(Bad Cait, no cookies, build the box-shaped one FIRST and get that one figured out....)

I like it! Nice and simple. On idea comes to mind; have a slide out galley that occupies the standing area while travelling

Interesting design indeed. :thinking: I like the concept so far! :thumbsup:

Thanks for the comments! :)

I have been refining the details, mainly how it seals the joints when open, and it's looking good. This design gives the most room with the least complications, and has plenty of storage when closed for items such as a Drifta-style pullout galley.

There will be an awning/tent off the back for more space; the trailer is mainly for secure sleeping quarters and a way to haul "stuff."

Opinions requested on width: wide enough for a sideways queen (7' exterior), a short queen (6'-6" exterior), or put the mattress lengthwise (5'-4" exterior)? I want it to be easy to haul into remote places, but not looking to do any super-hard off-roading with it (pintle hitch stuff).

Trying to keep myself from adding a slideout bed... the extra space it allows is nice, but I'm trying my best to keep it simple. :thinking:

If your looking for off road portability - my suggestion would be 79" wide - just short of the 80" extra lighting rule. Seven feet wide is HUGE and i foresee some problems getting into some off road places. As a general rule - if your Tow vehicle fits down the path - then your trailer should not be any wider than the TV. The Ladybug WW is 76"wide on the interior and the queen sized bed is lengthwise. I'm 6'0 and fit just well with plenty of legroom

Had a thought to reverse the plan and move the door to the side, allowing a slide out galley-type thing at the rear. An awning attached to the roof would keep water off the kitchen area, and one on the side would provide additional outdoor space. The bed is a sideways short queen (with no visible means of support), and there's almost 4' between it and the front wall.

This also allows the water tank to be over the axle, and the galley cabinet to be inside (at night) without taking up floor space. Top of cab is right at 3', so that works out well...

I like the rear bed, better.

You could do the galley in two drawers and still have a brace under the bed. As well as two short drawer/cabinets under the front edge of the bed.

"L" shaped cabinet with a lazy susan in the the driver side, front corner. A removable table between the cabinets and bed would create a dining booth.

Simple, spacious, Cool!

The only problem I see with your design is holding the top up while pulling the rear wall up. A top that size would be quite heavy and I'm not visualizing any way to add a lift assist system to it.

Other than that it looks great.

The top may well be heavier than I would like, especially without resorting to some type of cell-core panel. Nice, but pricey. If the roof is too heavy to use the simple Esterel system (gas struts), then the ugly system of exterior lifts could be used:

The width is still up in the air, as I'm not sure I like the idea of a short mattress. The extra lighting requirments for >80" don't seem like that big of a deal to take care of. My current tent trailer is 7' wide, and I agree it looks huge, but it's not a whole lot wider than the Tahoe pulling it.

I feel pretty good about it when I see folks weaving their 35' long 8' wide toyhaulers through the trees (with their 25' long crew cab diesels)...

Ya know right after I wrote that post I remember those lifts from my sons old popup trailer. they would probably work. Sounds like you got it figured out.

A RV slide-out room jack may do the job of lifting the roof section.

What about keeping the door in the back and a slide out galley from the side? Slides from under the bed. :thinking:

Could have one on each side. Either a galley or easy access storage.
:yes: :no: :QM
