Got a reply back from HC..$50 for an invoice, no data on the build or WB...
I tried to get back to it today, walking on the 4 ft of snow off the shed roof. It held until I was at the front bumper and could see I'd need to dig out next to the door to get it open. That's when the snow collapsed and I was up to my waist... I might try my wife's new snow shoes tomorrow...
