I know what it is. It's good but, you have to make sure the lift pump is running off the batteries instead of the factory ECM lift pump power lead because when the lift pump starts to go out it places excess load on the ECM and can burn it up so it should have the original power lead from the ECM going to a relay that it can trigger a relay that runs the lift pump off the batteries. It's an easy fix and there are simple aftermarket harnesses you can buy. Too bad this forum can't allow me to recommend good vendors.
Anyhow it may be already set up with the harness, you just have to see where the lift pump power is coming from and note the location of the relay. Sometimes when the lift pump goes you should change the relay (carrying an extra one under the seat) because it may be that it's a bad relay instead of the lift pump.
BTW, don't go for the leveling springs that lift the front a couple inches. It gets expensive to do it right and messes with the steering dynamics. Even when you go with all the upgrades to do it you will regret it. I have 2 second gen trucks, been hauling 2425 lb camper (dry weight) for 20 years on a single rear wheel camper w/o problems.
