I took one of the struts off today and it was rated at 90 lbs. I called Camping World today and talked to their parts manager. They sell up to 120 lbs. lift. It's a good hour to the nearest Camping World so I went to the Autozone nearest me. I got a strut the same length, but it didn't have the rating on it or the container. The clerk looked it up in their system but couldn't find the rating in the computer. The shaft was nearly twice the diameter so I bought two and figured I could replace both existing struts and if that was too much I could use one existing and one larger one. However, I installed both in place of the two that were original.
The mattress was so heavy that even with two 90 lbs. struts, the bed wouldn't stay in the raised position with the originals. While the new ones aren't a two finger lifting operation, the bed is much easier to lift and will stay in the raised position on its own.
Not sure why the manufacturer that Autozone uses doesn't include the lift rating, but they didn't. The Lift Master that was original had the lift rating on the side.
