ARANA C16-08055 20 inch 120 lbs Gas Struts Lift Support Prop Spring, 20" RV Bed Shocks for Camper Bed Cellar Door Travel Trailer are Fiberglass Topper Truck Bed Cover, Set of 2(NO Brackets)

Good item

We replaced our RV bed in our Grand Design 295 RL 5th wheel with a real memory foam mattress and factory lifts just weren't enough to hold it up. These were super easy to install and I was able to use the existing mounting hardware. It is easier if you have one person hold up the bed and replace one side at a time. Now we can lift the bed with one hand, pops right up quick, and it will hold it up in place! These are also way beefier than the factory 80# ones. This is the best money spent if you are upgrading your RV mattress!

The struts work perfectly (very high quality), and when I had a problem, the customer service was amazing. Fantastic company--you will be well taken care of if anything goes wrong. See below for details on how they went above and beyond to help me resolve a problem of my own making. I bought these struts for a large storage box I built. I messed up the lid weight and ordered struts with too much pressure. I estimated the total weight of the lid, which was wrong. I needed to measure each side of the lid where you plan to place the strut. I also mistakenly thought both struts combined were 120 lbs, when in fact it is each strut individually. All that to say, when I installed the first120 lbs strut the lid wouldn't close. Had I read the produce details more closely this wouldn't have happened. After taking a more accurate weight of the lid by measuring each corner, I emailed the company about the problem I created and asked if they could help me replace the the struts I ordered with a lower pressure set. Despite everything being my fault, they offered to replace the struts at no cost. New struts arrived within a couple of days. They were the right pressure this time and provide incredible support for the heavy lid on my storage box.

works really well, on my fiberglass bed cover it's heavy and the shocks work very well

It’s not at all clear that this doesn’t include the necessary mounting brackets for the top and bottom of the struts. You have to order them separately.
