First let me say - WOW. well thought out. Well executed. WELL DONE! I want to focus in on your camper lift, sorry if I am resurrecting an old subject for you! Could you possibly ad some detail on the frame you built to support the shell, as well as the chain and connectors. Thanks again for your post, its been enlightening
Thanks for the compliment! Also, I'm always willing to talk about The Shrine.
As for the frame, I had specific needs in mind. I am disabled and spend some of my days unable to stand...much less lift and install a 200 lb. topper/camper. My "work around" was to measure the dimensions of the camper and cut 1" square channel tubing 4" longer than the width of the front and back of the camper. That extra 4" would give me room to drill and attach eye bolts on each end for the cables and not risk marring the surface paint during the lifting. Then I simply drilled a hole centered in each front and back tube and attached another 1" square channel to keep the distance true, front to back, while in the air. The center channel length was driven by 2 other things: 1) the width of my tool box that stays on the lift when my camper is on the truck and 2) the folded dimensions of my JEEP's soft top. The soft top almost always stays on the lift.
Once those dimensions were established, holes were drilled and eye bolts installed. I used braided steel cable (300 lb.) and cut 4 equal lengths, put loops on all ends, used crimp connectors and tested the balance with a few 2X4s. It is surprisingly "self balancing".
The engineering was relatively simple or I'm just lucky but there are some important tips I can make. To keep the braided cable from marring the camper surface while suspended I used insulated pipe wrapping and that proved insufficient. The weight of the camper eventually compressed the foam to paper thinness and almost scratched the camper surface. My fix was to insert the braided cable in PEX tubing then wrap that in the foam pipe wrap. The displacement of the weight between the PEX and the foam was just right and remains effective after 5 + years.
Finally, the lifting procedure is this: I use a small floor jack to lift the front section (From the inside of the camper) just enough to insert the front tube w/ eye bolts facing up, then lower the camper on to the tube. Then I move the jack to the back (tail gate area) and lift it just enough to insert the rear tube. While the rear is lifted and the front is down (stable) I then attach the center "truing" tube to the front then the rear then, and only then, do I lower the the jack and attach the cables to the eye bolts and winch. It can be off a couple of inches front to back. It doesn't matter..it'll level itself out once it is the air. Also, if you are lifting the camper be sure you have a hand on the unit BEFORE you lift. If you are not parked exactly centered/below the lifting motor when you lift you could find the camper lifting and swinging toward your rear window. A little swing goes a long way if not controlled. Lowering is easier in that you can set it down exactly where you want it with a little tug here and there.
I used a Harbor Freight winch w/ a self locking mechanism and merely extended their 10' length operation cord to 30 feet. My ceiling is 24' high and the extra length gives me the ability to walk around the the camper as it lowers ensuring a perfect landing.
I hope this helps and thanks again for the compliments!
