Good news...freightliner replaced the elbow on the air line, that I expedited procurement of, and dashed back over to FR and Randy got all of the remaining issues fixed. Including replacing the furnace...we will put it to the test tonight to ensure its reliability at the Elkhart Campground before departing tomorrow. Randy's crew really stepped up to the plate prevented us from having to go back and finish up the next day!
Furnace ops check was 4.0! It cycled in and out of the set temp within 2° and is keeping it nice and cozy. Thanks all for your concerns as always and now we can get moving...maybe today or tomorrow, DW wants to clean since there has been so much maintanance activity.
