I received the 36# strut today and put it in. It holds it up.....barely. As in "only when it's all the way up, and without the cargo liner." If I nudge it, the whole thing drops. So, I reckon the 40# strut isn't going to cut it. I'll be ordering a couple of the 50# units to see how they fare.

I'm running into the same issue on my 2018 Suburban. I pulled the unit (APY22145) and since it's the same P/N as CS15DAH had, I think that is an OEM part. Overall the length between pivots is 12.6" and the closed length is 8.8". This means the stroke is 3.8". Based on my measurements, the actual stroke needed to close is around 3", so there's some flexibility. It uses a 10mm ball mount, which seems very common. I have a quick drawing below. I found a couple of options on Amazon. The first is by BOXI and have almost identical dimensions. Lifting force is 36#, which is about 12# more than the ones CS15DAH found in the post above, which is the lower-end of what they thought was needed. They come as a 2-pack for about $20. (https://www.amazon.com/gp/product/B01HLYT2J2/) The second is by Pamagoo. They are about 1/2" shorter (12.2"), have a longer stroke (4.7") for the 35# version. They're available in 35#, 40#, 50# and 65# versions. Some have slightly different lengths, but all have at least 3.5" of stroke. They come in 2-packs and range from $18.50 to $22. https://www.amazon.com/PAMAGOO-C16-25563-C1625563-Replacement-Toolbox/dp/B0B256B75L/?th=1 I think the 50# and 65# versions are probably overkill, and might not let the cover stay down. My truck came with a WeatherTech cargo mat, so it'll have a little more weight. I'm going to order a pack of the BOXI struts and see how it fares with and without the mat.
