Turnbuckle Blues

In the just more than a year of Pop-up truck camper ownership I have spent more than 30 nights in the camper with my wife and 2 small children. From trips to the river, boondocking next high Sierra lakes located up remote 4x4 trails, huddled inside cooking and playing cards next to the heater when the mountains dealt us a surprise fall snow storm. To a week spent meandering the California Cost from Santa Barbara to Santa Cruz and every beach and coastal range mountain hideaway in between, and day trips where a toddler needed a quiet shady nap, or when a potential day ruiner, like a surprise mud puddle was solved by a warm outside shower and well stocked wardrobe inside; we have come to consider our camper not just or best gear purchase, but our best family decision for bringing us together and creating memories.

In the 14 months, 15,000 miles and 30 nights or Hallmark/F250 combohas not let us down or shown any sign of breaking a sweat except for one small exception; the turnbuckles. I have bent and broken turnbuckles, straightend the hooks when CalTrans misplaced a steel trench cover, had to reposition the camper when it came lose while tackling a particularly rutted trail. In general they have detracted from the family overlanding bliss

In my short time as truck camper owner I have decided that the turnbuckle system we use is not ideal for off-road travel. I’ve upgraded my hardware with lock washer and lock bolts but still find myself adjusting at every gas stop. I’ve spoken with the good folks at Torklift and they advised me that off-road use voids the warranty so I’ve eliminated them as an option. I stopped by Earthroamers facility on recent trip to Denver and it’s seems that they have the perfect offroad mounting system (frame mounted in the front, articulated in the rear) but you lose the versatility of having a pick-up truck when the camper is not removable (although astoundingly perfect machines I still haven’t processed the price tag). And lastly I spoke to a tech at Fourwheel campers. When I described my problems he told me that in the old days they used to have a bolt that went though the camper and into the truck frame. He said this was by far the best connecting system except for the fact that it was extremely difficult and time consuming to mount the camper. One could spend an hour plus shimmying the camper trying to get camper and truck bolt holes to line up.

Despite the caution I’m beginning to think a direct to frame mounting system is what we should be looking for. Has anyone custom made one or heard of a product that allows this but solves the problem of alignment and quick mounting?

What about those fastgun things that people rave about on the rv forums. from what I've seen they look like those levers used on log trucks and such for securing the load. So you adjust them to length then just move the arm to hook and unhook instead of turnbuckles.

If you are happy enough with the turnbuckle system, with the one exception being that they get torn up, maybe you simply need to step up to a better turn buckle.

I run galvanized steel turnbuckles on my flatbed camper. It would be easy enough to install a stop nut on one side of it to eliminate any loosening. Ive thougt about doing just that, but Ive got more than 6k miles on them with the camper, and I have yet to find them loose.


They were expensive thought. I think they were nearly $25 each. But they are rated at 3k lbs each. Where a similarly sized aluminum buckle would be rated at less than 1500lbs each.

I've been careful not to over tighten the turnbuckles (hand tight only), and put wing nuts on the turnbuckles, and I have no issues anymore with mine.
 
My FWC is bolted through the bed of the truck. Not into the frame but just the sheet metal (which I feel is plenty strong enough to hold the camper in place). I had a little bit of deformation of the sheet metal from tightening the nuts a little too much. I solved this problem by placing an extra piece of steel on the underside of my truck running the distance between the two front bolts. I can now tighten the nuts down very tight and not have to worry about metal deformation. I also decided to use two turnbuckles just for a little extra support. I only have to retighten the bolts about one time every mid season (lock nuts). With six mounting points you could turn my truck upside down and give it a good shake and the camper wouldn't move.

See post #45 to see what I am talking about.

As for lining up the bolt holes when you first put your camper on in the spring….the first time I did it I had a hard time. I was only off by a very small amount. I took a rat tail file and bored out the hole just a little bit to get them to line up. This past spring when I put the camper on everything lined up perfectly. I leave the camper on all summer because it's just to much of a hassle to take it off and put it back on. I have a trailer when I need to haul anything large.

I would agree with this.

The turnbuckles that are used on boats are under huge stress. Some of ours are under a static load of 10,000lbs, I forget what the working loads are, but it is many, many times the static load.
