I would be happy to help!

The only difference between the Brophy Cable Camper Jacks # CJ31 and # CJ41 is the weight capacity. The # CJ31 has a 1000lb weight capacity where the # CJ41 has a 3000lb capacity. Both have the same 17" - 57" lift range, so you will just need to pick the one rated high enough for the weight of your truck bed camper/cargo box.

I included videos of the products mentioned for you to take a look at.
