check the cupboard door 31QBS
the shipping weight is posted on a door in unit. Don't go by the brosher as mine said 5390lbs, at dealer it was shipping weight 5540lbs. when I weighted it it was loaded with just battery, full propane tanks(2-20lbs.) and power jack and it was 5920 lbs. 600 lbs different. I later found out that the battery and tanks were not included in shipping weight.
So it will be Take to scale to find out. They need to give an real accuate weight info when they(dealers) sell.
The weight from factory is probably right
but dealer should have to tell the extra weight amount that is added.
