What do you mean backs up? Is the lower hose collapsing when it's running?

The temp gun will tell you if the gauge is in the ball park are not. If the gauge reads 206 and the temp gun pointed at the senor reads 190 then you know it's in the gauge.
As stated it will give you some good info on the temps at different points of motor.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
