Simple Operation

Using these jacks is simple. Place 1 jack on each side of your camper and position the L-shaped lift brackets underneath the body of the camper. Then crank the hand winches to lift or lower each side of the camper evenly until the proper height for loading or unloading is achieved.

It is recommended that 2 people operate the jacks simultaneously to make it easier to raise each side of the camper evenly. However, 1 person can do the job by alternately lifting or lowering each jack in small increments.

Video Transcript for Brophy Cable Camper Jacks Review

Randy: Hey guys. Randy here at etrailer.com. Today we're going to take a look at a set of in-bed camper jacks or lifts. We get questions about these all the time. How effective are they How do I use them How I put them together So we're going to go over all that, but something I really like about these is that they are very, very compact and very easy to store when not in use.When you see something like this, you generally think, where am I going to keep them How am I going to keep them stored As you can see, once we break these down, they're really nice, small and compact. So we can very easily tuck these off to the side and really only get them out when we need to use them.As far as assembly goes, it's really going to be pretty easy.

You can see our tripod there, got a shorter leg here. We want that to be out and away from our vehicle. At that point, we're going to grab our main lift tube. You just want to slide that right through and into the base. At that point, we grab a hold of our winch cable.

We're going to back this off till we can place it around our pulley at the top. That's really all there is to it. We've got it assembled. We've got it ready to go.A few tips for using these. We always want to make sure we're on a good level surface, and we want to make sure that it's a solid surface.

I would definitely recommend, if you've got any kind of soft ground at all, that you use some kind of stiffening device underneath it. So, nice 3/4, 5/8 piece of plywood, something like that, just to make sure we don't have one leg sinking down and in.Another common question we get is whether these need to be used in pairs or if you need two pairs or if you need four of them. And they recommend as long as you're staying within your weight capacity. This is part number CJ31, so this is going to have 1,000 pound combined weight rating, 500 pounds a piece. So as long as your camper's under that 1,000 pound mark, one set's all you need.

You're going to bring them in, position them and slide them right under the edge of the camper. Got that release. At that point, we just crank our handle to lift them up.Now, it's important that you find the center point of your camper. If you've got them too far forward, it'll want to tilt back. Too far back, it'll want to tilt forward. So you just lift it a little bit, make sure it's balanced on there properly. But at that point, you just need to lift it up a few inches. Once we've got it lifted up, we know the top bed rails of our truck are going to clear. Just pull on out. At that point, I like two people doing the job. You can have one guy on one side, one guy on the other, and you can lower them down kind of at the same rate. If you don't have a second guy or if you don't have extra set of hands, that's okay. Just want to do it maybe 8" per side. We'll lower this side down about 8", lower that side down about 8". You just get it lower down there to the ground, so it's not so tipsy, it's not so top heavy.Overall I think they're going to do a really good job. They are tried and true. This style of lift has been used for about as long as in-bed campers have been a thing. The construction I like, just at first glance it looks like maybe it's a little flimsy or there's no bolts that hold the pole in, so that can be an area of concern. But no issues with it at all, it works really well. It works very effectively. I've used these several times and never had any issues with them.The crank handle itself. We've got our release gear there and actually click as we're going down, just easy to use. Just like the winch on a boat trailer. inaudible 00:04:00 the winches are rated at 1400 pounds. That doesn't mean all the components are, but it's overbuilt for this application. So it's going to work out really well. Got a black painted finish on everything else here at the top and the bottom with our tripod, and then of course just standard galvanized pipe here.In working with a few customers up north, in-bed truck campers seem to be pretty popular. I think they're popular everywhere, but up north, it makes me think of corrosion. They've got a lot of salt and a lot of stuff like that. Winter seems to last about 12 months, but really no issues with corrosion on them. I think down here, if they're underneath the snow for awhile, at your feet, you might have issues there. But all in all, it's going to be a nice solid way to get that camper lifted and get it lowered back down and really save a lot of the backbreaking work.Now, these can be used in other applications as well, like pickup truck toppers or pickup campers, not in-bed campers, but like camper shells that go over the top. We get questions a lot is do other, you can use these for that and they work out just fine, haven't had any issues there. I don't know of too many other things that you might use them for. We have had questions in the past about kind of some raised platforms and stuff like that. But I think as long as you're staying in that in-bed camper or that truck topper, camper shell kind of area, you're going to be in really good shape and they're going to work out really well for you.Now the area our camper's going to rest on, our landing pad here, this is going to be 21-1/2" long. Comparing it with a lot of the other ones out there, it's right in line. So I don't think you're going to have any issues, give us plenty of room to get that weight balanced out here on top. And once you do find the balance point, if you're doing this just for the first time or it's your first time using a set of these, I always like to indicate on my camper where that's at. You can even mark on the bottom there as long as you can see underneath it and just give yourself an idea. The next time you put these in place, you'll be right there in that safe spot where you've already tested it and you know it's going to work out for you properly.Now with trucks kind of getting higher and higher, the bed rail side seem to be getting higher and higher. You will need to take a measurement on your vehicle and just make sure that you're under, say about 55" is probably the maximum you'll want to be at at the top. This has the lift potential of 57", so gets us up there quite a bit. If that's not tall enough for you, if it's not high enough for you, the option we have for you would be CJ74. That's going to be a 67" lift model, but it's also a 3,000 pound capacity. So you're going to be moving up in capacity as well as up in height, but it should give you that additional room that you need just in case you do have a taller truck. You need to get up there on it, that would be a really good option as well.Guys, I hope that kind of answered some of the common questions we get on these and the best way to use them, how they're going to work and how high they're going to go. Overall, if you've got a truck bed camper and these fit your requirements, I think it's a really good decision.

These things do the job, do it well, and don't take up a ton of space when not in use. I love these jacks. 662709

- CJ31

Best price on the internet... that I could find! Great directions, assembly was painless, worked perfectly. My son bought an old 70's metal framed camper shell that was at b*tch for 4 grown men to lift. I figure it weighs 500+ lbs, maybe 600+. These jacks worked absolutely perfectly. Lowered the camper onto saw horses, and I'm sure it will be just as painless to remount that beast. Thanks etrailer! 313139

- CJ31

This was just what I was looking for. The jacks are well made and very sturdy, attention to details and assembly is easy. I have purchased several items from etrailer in the past and am pleased with their service. 613524

- CJ31

I have a small slide-in camper that is about 750lbs for my Nissan Frontier and these jacks work great. I previously had the larger jacks, so moving to the 1000lb ones was a little bit of an adjustment since they have a smaller base and platform to hold the camper, but the ratcheting mechanisms have a safety on them and are very solid. Other retailers sell the poles and jacks separately, and I appreciate that ETrailer bundled them together. Will share a photo when I get the chance. 443760

I bought these jacks to lift and store a pick up cap (some call them toppers) in my yard. Combined with 2 saw horses and a few 2 x 4s these jacks worked great. Since they were used outdoors in a New England winter I covered them with large plastic garbage bags and then 5 gallon buckets over the bags to keep them from blowing away. The jacks fared very well and the only rust that appeared were on the feet where I'd expect it. I would recommend these jacks for those looking to utilize them in similar applications. They are well made and sturdy. 700233

- CJ31

What was really great, was that I had placed my order and etrailer notified me that it had been shipped! I was greatly pleased with how fast they handled my order. Tracking was easy and delivered on schedule. The jacks are first class and do just what I need. Easy to assemble even without looking at the instructions. One minor complaint is the way the crank handle is shipped. The plastic sleeve on the handle part gets sliced so that when you grab hold of it, you notice a definite sharp edge. Some sanding took care of that issue. Overall, I give etrailer a thumbs up. I know where to go for future purchases. Great value prices and fast shipping. Thanks to all involved! 271372

Ordering was easy, delivery was prompt. I would do more business with this company. The are very professional in every way. The Jacks do everything I want them to do. 615235

- CJ31

fine jack - smooth operation, balances toppers readily (may seem tipsy, but they remain well supported). One recommendation - suggest developing a right and left oriented jack, specifically have round cable pulley wheel on different sides. Currently the pulley wheel gets very close/can rub side truck side beds on one side. 607780

You people were fast. Received product within a few days. Will have to say..the box is not good for shipping..held together on two sides..but product too large to fall out. I am very pleased with your service and price. 501455

- CJ31

My son now attends college so I needed something to help me remove the camper shell before loading up the cab over camper. These stands make it possible for me to take off my off the camper without any help and eliminates the need for me to roam the neighborhood looking for help. 469949

The jacks are great, just like the ones I had years ago. My problem is they work great for a "camper" not so good for a "camper shell". They need to be four inches taller. 315189

Good product at a good price. I've used the Brophys many times now and they have always performed as expected. 271938

The jacks still work great after a year of use. Im very satisfied. Great job at etrailer on the follow up.

  • Can the Brophy Cable Camper Jacks Lift a Camper Shell
    As long as the bed rails on your truck are not more than 57" from the ground then you could certainly use the Brophy Cable Camper Jacks part # CJ31 to lift the camper shell up from your truck bed. Once lifted, you could just simply drive away and the camper shell will be left standing. This is certainly not the intended purpose of these cable jacks but if it were my camper, I would want two jacks on each side for support.

  • 57 or 67 Inch Tall Brophey Camper Jack Recommendation
    If it were me I would go with the taller 67 inch Brophy jacks part # CJ74. Having more height than needed would be better than not having quite enough. Plus your truck does sit taller than most similar sized trucks so the extra height would be beneficial.

  • Can the Tripod Foot of the Brophy Camper Jack CJ31 be Positioned Out of the Way
    The Brophy Cable Camper Jacks # CJ31 has tripod feet with the longer two legs sitting at almost a 90 degree angle in proportion to the smaller leg. Since they don't sit at a perfect 90 degree angle they will be slightly under the L-brackets that you will be lifting with. This should not be an issue though as the the lowest height the brackets can get to is 17 inches.
