I have cabin fever too. Yesterday I went out to the storage lot. Got in my 40' DP, turned on the furnace, and just sat there for a while. Then I cranked the cummins and she fired right up and settled immediately to a low clatter....
I remembered a couple years ago when we wanted to go somewhere in the early spring and the jacks were frozen to the ground, so I hit the retract button. Sure enough, one was stuck. I got 5 gallons of hoy water and got 'er free'd up. I put the Allison in D and moved her forward a foot to make sure she wasn't stuck.
Then I shut everything down and locked the door. But I feel much better now.
