The only reason to keep the trailer level, is for the reefer to work properly.
It's off level limit is 1/2 of a bubble, front to back or side to side.
If the reefer will not be used, then being off level doesn't matter.
For long term storage, for the larger Airstreams, use 6 jack stands.
Place 2 on the A-frame, just forward of the shell.
Place 2 on the frame as it enters the rear banana wraps.
Place 2 on the axle mounting plate, between
, on the axles.
