Being perfectly level without a hydraulic leveling system is tough side to side. If I can get within an inch side to side Iím happy, Ĺ inch if Iím staying for more than 4 days. Front to back, is done with the tongue jack so that direction is easy. I think seasonal people level slightly better even blocking their frames in several locations.
Those stabilizers on the corners of the trailer are not for leveling but can be used for fractional leveling. There are several TT owners who have added an extra set of stabilizers near the axels; I think all who have added these have trailers over 25í. I through the cheep flexing crank handle away and use a nice solid crank allowing for extra torch, to speed things up I have a cordless drill but it doesnít always give me the torch I want.
I believe leveling for the fridge is the most critical and that is mostly side to side of the fridge. Early on, I put a level in the bottom of the freezer and adjusted the outside levels to that location. I believe that the levels installed by the manufacture are installed to look square to the location of installation and not necessarily level.
I keep a squeegee in the bathroom for those many unlevel times
I often sleep in parking lots on the way to where-ever and trying to find a level spot is impossible so I try to park the nose low and block the back tires on my TV to get level-ish.
Getting level is one those camping things that you get better at with time as well become tolerant too not being. I installed a large level that can easily be seen from the driverís seat and use wedges to drive up on.
I know itís a bad picture of the level but itís what I had handy, itís there in the middle.
Just think if you lived on a boatÖÖ..
