We have a V-lite 26 FKSS. I put a 2 way adjustabel level on the tounge just ahead of the jack. I adjusted the bubbles off so with the slides in it appears level. When the slides go out the bubbles will be off, but the unit is leveled. Took a couple of adjustments to get it just right.
I also shoot for somewhere between a half inch to an inch on the slide side, this will usually bring me almost level. They also put for screw jacks under the frame to help stabilize the trailer along with x chocks.
It is an estimate and varies every we set up most likely due to what some else said about pads not being perfectly level. I have been getting ours pretty much spot on using the estimation method until this week and I deemed it level enough based on the bubble and unhooked. When the slides came out I was way off. I just slept with my head downhill......
I had the V-Lite version of your camper and very early on had noticed the tt out of level after extending slides. I always would check the level of the camper prior to any set up and most times trailer was not level on slide out side. I started using a 2x6 board placed on slide out side. Also I would extend the stabilization jacks before putting the slides out. Never had an issue after with cross level from then on. Later RJD

Funny you bring that up. I put two levels on mine one for parking it and the other for when the sides are extended. This works for me. I also, for me, notice when you walk in it it tilts somewhat. So I tried to use the leveling jacks as high as I can using the giant Lego blocks. Maybe someone else has a better idea. It this is confusing I retry to explain
