Newbie fed up with so much misinformation on set up of a TT

I also put my levelers under both wheels. I open the door and put a level in front of the fridge, and add leveler blocks until level. If your stabilizer sissor jack is extended to the max or near max, then put some scrap lumber or something similar under them. I always put a 2X6 under mine regardless.

After a day or so, things settle, so recheck the stabilizers.
