From your neighbor down the road from you, YES looking at you pictures that counts for camping/testing. Sounds like you are having FUN
Nice Rig !!! Yes,? our weather has been weird, think forcast is for a couple more inches of snow.. Not sure when pictures were taken?? See no foot prints so I believe you are comfortable in there.
As far as the propane tanks, only issue I see is with keeping one closed is running out in middle of night and having no heat
Not sure if you have an automatic propane switch over valve and indicator on your rig. If so, you can keep both values open and View that indicator periodically then refill empty one as needed.
Just curious, are you still winterized or are you also testing the water systems including your tanks
Never hurts to test, test ........, before you hit the road
