Lifting your truck camper on and off of your pickup truck is challenging if you don't have the right equipment. This pair of reliable cable jacks helps you load and unload your camper with ease. No permanent installation is required, so you won't have unsightly and expensive electric jacks hanging off of your camper. And because these jacks break down into 3 portable, easy-to-assemble pieces, you can take them everywhere the road takes you.

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.

We bought the jacks to remove our camper shell. The “L” shaped supports for lifting the camper shell were a little small for a camper shell so we had the kid across the street weld on a piece of steel to extend it in order to lift the camper shell. Works great and we’re happy with the jacks. Eric.

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.

Packaging was very poorly done and the powder coating on the bases and winches was pretty dinged up straight out of the box. For the price I was hoping to get something in pristine condition. I looked passed that and tried to put my camper shell back on my Tacoma. This easily lifted the shell and although it was pretty wobbly it didn’t feel super dangerous. As I’m backing up Its obvious my Tacoma was too wide to fit between the base and the poles so I backed it about half way under the shell and had to pull the shell up to the cab the rest of the way by hand. The bracket that goes under the shell beat up the fiberglass on the camper a little too. Still better than trying to lift it with a friend but not what I was hoping for. Would not recommend this to a friend.

- CJ31

The product: excellent, well built, easy to use. The packaging: to put it bluntly, sucks. The box with the tripod feet and pulley assemblies arrived nearly destroyed, held together with a few strands of cardboard. Luckily, the product pieces themselves are nearly indestructible, and are large, so nothing fell out. I like your product selection, prices, and fast shipping, but I doubt I will ever order a large heavy item from you again. Don't want to press my luck.

Not tall enough for my truck

Hi Scott, Thanks for your feedback! We do offer cable jacks with a 67 inch max jack height. I would recommend the Brophy Cable Camper Jack - 67 inch Max Lift Height, part CJ74H .

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!

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.

- CJ31

I have had these jacks for a year now while building my own slide in camper. They have been great Very easy to use and also to store away. Just bought another two because of the weight of the camper now.

- 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!

- CJ31

These work great for me lifting off my S=250 Comm Shelter

- CJ31

Bought the jacks to use for installation and removal of my Leer truck topper. It did a good job! Item was shipped quickly. Excellent service.

I have had this product a year now and it is still working great.

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.

- CJ31

These jacks were the perfect solution to allow me, a 70 year old guy, to take the canopy off of his Ford F150 by himself. The jacks were delivered as promised and were packed appropriately to avoid any damage. I have already used the jacks and my canopy is now off for the summer of soil and mulch hauling for my yard. My canopy is sitting on top of concrete blocks where it was a cinch to position them.

- 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.

- 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.

- CJ31

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

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

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.

- CJ31

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.

- CJ31

Jacks are well built , worked great ! Great company to deal with !

- CJ31

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.

- CJ31

Good product, handled my 900+lb slide in with ease... Reasonable price.. Packaging could be better...

- CJ31

Best price. Got here reasonably fast. Easy to set up and use.

Ask the Experts about this Brophy Camper Jacks

  • Distance from Upright Mast of Brophy Camper Jack to Bracket that Holds Camper
    I checked with Brophy and the Brophy Camper Jacks # CJ31 have a distance of 3 inches from the upright mast to backside of the bracket that would hold your camper shell.

  • Will Cable Camper Jacks Flip Truck Camper When Being Used
    There is no danger of the Brophy Cable Camper Jacks # CJ31 flipping the camper over when you are using them; you just need to ensure they are properly used and aren't overloaded past their 1,000 lb (combined) capacity. These jacks have a tripod base which means the weight is evenly distributed so there isn't going to be any movement, and the winches that raise and lower the jacks have safety latches to ensure you can maintain control at all times.

  • 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.

  • Can Brophy Cable Camper Jacks # CJ31 Be Used to Stabilize Truck Camper

If you plan on using the camper when it's off the truck you will still want to use some kind of floor support as well. These two cable jacks feature a combined weight capacity of 1,000 pounds and...

  • Light Duty Brophy Cable Camper Jack Options
    If you're needing the 67" max lift then you can get two of the 1,500 lb version # CJ74H. Same Max Lift just half the weight capacity. If you do not really need up to 67 inches of lift, you can get the # CJ31 that will have a Max Lift of 57 inches and a capacity of 1,000 lbs. These are both great options that are more light duty than the 3,000 lb jacks # CJ74. I've included some videos for you to check out if you wanted to learn more!

  • Jack Needed to Support Slide Out on 2018 Passport 2810BH with No Rails Under Slide Out
    Since you don't have the rails under your slide out the typical slide out supports like part # UF19-960003 wont' work but we do have another possible solution for you. Brophy has some camper jacks that are meant to be used for supporting a truck bed camper but when I spoke with my contact at Brophy she said you could use them for your slide out too. These come in varying weight capacities and max heights so you would just need to choose one that fits your application. Please note...

It is designed to replace the Brophy cable camper jacks part # CJ31 part # CJ41 and part # CJ74. However, I have attached a diagram for you to compare this handle to your handle.

You would need at least 2 of them. Each is rated for a total of 1,000 pounds so make sure that your camper is under the capacity total.
