Timbrens or ?? For Truck camper

[2020 Rebel]

Getting a lighter truck camper this is acceptable for the load rating on my RAM and was wondering if anyone has used this kit Timbren SES Suspension Enhancement System SKU# DRTT1500 - Rear Severe Service Kit Looks soo simple makes me over think that it can be this easy ?? This is the NEWER kit made specifically for slide in truck campers

I have investigated and looked into Timber Grove ASAM PN #SQ7729456, but many have mentioned that they are "kinda" bouncy with the required 5PSI min required to run them even when the bed is empty??
