We got tired (pun intended) of sleeping on the stock cushions. We had some custom mattresses made. They are 9.5” thick, and very easy to move around when accessing plumbing/electrical. They are high density foam, so much lighter than latex. These are firm, and amazing. Custom Comfort Mattress in Southern California

Those look very nice!

Just ordered mine at O'Reilly's. Supposed to be in next week. June 1st for spring and shock replacement

I have a 2020 model with the Norcold. I have attached some service manuals I found that might be of help. I found them back when I changed out a power board. Hope they help. I never tried doing what you are doing.

Some of mine look like that. There's a couple of threads talking about alternatives to the Monroes.

It's likely those shocks are shot.

I would replace the entire shock. The cost of the shocks was not that much and I expect yours are pretty well worn out. I replaced mine on my 2020 trailer about two years ago and what a difference it made.

Thanks for this post. I just completed the install the same way as @tallmandan. I would like to add that my attachment was very difficult to unscrew. Not sure if four years ago GM/Chevy made them differently...but mine had lock tight in the screw attachment. I would advise anyone doing this install to be very careful while attempting to unscrew the attachment. The cable is power over coax. The attachment is just a crimped connector. I had to fold back the rubber casing and grip it very tightly with a wrench to get mine undone. If the crimped attachment spins it will strip out very easily!

Just received our Alcan Springs 5-leaf with heavy duty hardware. We will be having them installed as 4-leaf. Scheduled for first of June around a short Indiana trip. Will do the two 50 mile drives same day and they will re-torque, and then after our Indiana camping trip for the 500 re-torque.

@rideadeuce - A tip...Last year when we went to Alaska we bought some yoga mats and used some 3M no residue tape to attach them to the lower front of our trailer. They worked like a champ at keeping gravel from the Yukon highways from chipping the body of the trailer. We also used a roll of clear rug protection plastic from Home Depot on top of the Yoga Mats to keep them from absorbing moisture. Below: First week of the trip and the yoga mat's are doing well...tne extra coat of vinyl floor protection film is holding water at bay. F Below: After a full 9 weeks on the road the yoga mat's took the beating, but our trailer was protected. Below - After yoga mat removal and quick wash...

Good plan on tightening the shocks. First I heard of this model Monroe still holding pressure, especially when looking like that. Mine looked much better (AZ trailer) and 3 of 4 were totally shot and the 4th barely holding on. Too bad I did not know of the Bulldogs last fall. Your leaf springs, at least what's showing in the pics look nicely arced in very good shape.

I thought I would follow-up on this after my install. Might be helpful if anyone else has a 2020-2022 GM vehicle with the advanced trailering feature and is considering this accessory... Everything went well and it was easier than expected. The "transparent trailer" view feature requires that the camera be placed within a certain zone at the back of the trailer and on the Oliver, the only plausible location is to mount on top of the spare tire cover. @Cameron shared a photo above of the camera installation that Oliver did for him, and it looks great. I decided I didn't want to drill holes in the spare tire cover as the camera is not compatable with non-GM trucks and I might move to another TV someday even though I love my Silverado 3.0L deisel. The other challenge is that you must still be able to remove the spare tire cover if needed, so I needed a plan for either easy removal of the camera or lots of slack cable inside. As it turns out, I have both. There is plenty of room to run the cable in the channel between the aluminum crossbars and the fiberglass under the trailer on the curb-side. This is where the propane line is located and runs all the way from front to back. The cable is well protected and tied in with several zipties along the way. The plug-end of the cable that plugs into the truck bumper port can be unscrewed to make it smaller and now it fits easily through the gap at the back of the diamondplate bumper and fiberglass to route the cable into the storage area in the bumper. Then it is easily routed into the chanel where the propane line is to run all the way to the front. To scure the camera, I elected to use this high-strength plastic Alfa-Lock Velcro product that utilizes 3M tape. This allows me to remove the camera if needed and replace it easily yet it has a very secure hold. I will only need to remove it if I need to access the spare or, alternatively, I can leave the camera secured and pull the excess cable up through from the bumper storage space. Since the camera is mounted on a horizontal surface, this seems plenty adequate. Finally, I used a few stick-on plastic retainer clips to hold the cable around the outside of the spare tire cover. The look is not as clean and good looking as Cameron's install from Oliver but I'm happy with it and it seems plenty secure. I will see how this it goes this travel season. If the Alfa-lock Velcro fails then I will try 3M automotive tape and rely on pulling through the extra cable from the storage space when I need to remove the cover. Hope this is helpful for anybody else considering this accessory install. Dan

Here is a pic of the TPMS display in the cab. Can't figure out why it keeps posting sideways. Here are a couple other pics of the trailering software in the cab.

Here is the GMC trailer camera installed by Oliver service prior to pickup. They did a great job.

Here is a picture of mine. Oliver installed it for me at pickup. Ran the cable from the tongue, under the trailer the up through the top of the spare tire cover. The have the cable come through a little chrome piece. The excess cable is in the bumper compartment. John

I'd agree with this if the bottom leaf was an overload type that didn't make contact with the leaf pack until a certain weight was exceeded. With the Alcan springs the bottom leaf is arced and looks to be always adding stiffness to the pack. Could be wrong.. Good question for Alcan.
