Propane tank is in! My god that was not fun, its tight, like really really tight, cant lift the tank up, it has to be tilted and wiggled into place.... Apologize in advance for crappy pics, its tight.
The front side of the tank got through bolted through the floor, its under the fridge, which meant fridge had to come back out. Back side I couldn't do that as it would have been right inside the door. So I made some brackets, they go under the flange on the tank, pickup both bolts, and then bolt sideways through the floor member. Getting all that lined up with the tank in place was interesting.
Brackets with the lovely blue paint
And in place.
