I concur ..... this should solve your problem. I have applied smallish "stick-on" bubble levels on the front of our 8315BSS - one on the slide side and one on the front panel cap, both aproximately even with each other. As long as both of them are initially installed with the trailer "known" level with the slides not extended, you will be able to instantly see the level state fore and aft and side to side when unhitching and setting up. I have found that about 1/2 a bubble or so "high" on the slide side will do the trick after the slides get extended. Finally extend your stabilizers to a "firm" contact with the ground.
