We have the ground control 3.0 system on our Cougar. I thought it was rather humorous reading the operating instructions that said "start with a level site". So I always get the trailer as close to level as possible. First side to side using a tri-leveler

I tend to think of the 3.0 system as a "final leveling" or fine tuning of an already, fairly level situation
