The fit was fine, they were rated for 40lbs which is the correct strength, they were rated at 20" which from my research was the correct length, however when installed they were just a little shorter than the OEM. They hold the window up just fine. And for the cost savings it was a no brainer. Here are the shocks that I got from Amazon, Amazon.com: C16-08316 C1608316 20" 40 Lbs Gas Struts Prop Shock 20 inch for Camper Shell Rear Window Tonneau Cover RV Side Door, 2Pcs ARANA : Everything Else
If I was concerned about the slight difference in the height of the window when opened I might consider these from Amazon, Amazon.com: Sixity Auto Pair 2 pcs 22" 40lbs for Mobile Motor Home Camper RV Door Hatch Lift Struts Supports Props Arms Lifts : Automotive but you would have to buy the ball head studs and nut separately.
