First, I found something called silnylon, on ebay, its silicone impregnated rip stop nylon. I think that will work fine. As far as cost, I've got $200.00 into it right now and expect to spend about $300.00 more at most. On the size issue, i'm not sure what you're referring to, but to give you an idea: The top will hinge at the top front edge, across the width of the truck. It will rise up about 2-3 feet at back. Its just enough to give me head room to change clothes, etc. My truck is a short bed so the overall camper is pretty square. 77" long by 78" wide. I could have made it 78x78 but would have had clearance issues with the tail gate.
Sorry, I was specifically speaking to the fabric, size and cost wise. I am thinking about taking an existing box that is only 5'5" and putting a liftable roof on it. So the fabric portion is what gets my attention most.
I love your willingness to go for it on this project though! Very cool and certainly far above my head in the fabrication department!
I did a search on the silnylon... Interesting stuff. I found this link, also, that you may want if you have not read it yet. It is all about how to work with sewing the stuff...
Do you have any concerns about the insulative properties of this stuff? It looks super, but it does not look like it would hold the heat in at all.
I'm waiting to see this finished! For some reason, your first few pics gave me a VERY different idea for a rear slide-out for an SUV (open the lift gate and the tail gate, and slide out the extension to extend the length of the bed, to the edge of the laid-down tailgate).
Thanks for your comments. All are welcome. I have been thinking about this project for over a year now, and really couldn't begin to figure out the small details without starting it. As i have gone along, i have had to change some ideas, and add others. The air conditioner was a late addition. The fabric sides i have been considering may go by the wayside, as i am thinking i can get some hard sided panels fab'd up pretty cheaply. I'll just wait and see. Right now, the priority is just to get the overall structure finished and painted. This is where i am at now. Just some skinning left, and then seal and paint. Getting closer by rdraider72, on Flickr
