Just curious as to if there was any reason to have the entry in the front
and the lifting pivot point at the rear? It is more conventional to have
the pivot point in the front and the door in the rear - no need to
negotiate the tongue all the time that way, and less wind driven water
entry chances.
Hinging the Hobbit Hole door and sealing it will require close scrutiny
by you. Perhaps studying front loading washing machine doors could
help you figure out your details. [It may be worthwhile to try and check
out a commercial laundry repair place to see if you could even buy a
hinge off an out of commission washing machine or maybe even a
commercial dryer's door. Maybe even get a dryer door if it'd be large
enough to use.] ebay and appliance parts may be other sources.
I got curious so I Googled "front loading commercial washer/dryer door hinge"
in Images and came up with these as a possibility. A little $ here for
a purpose made round door hinge may be worth it.

possible and also gate hinges. You'd need a relatively larger sized
one as it'd be a single hinge carrying all the weight and movement forces.
I'd recommend integrating a top-to-bottom 2x4/6 onethe side you'd
mount the hinge on in the foam wall and tie that into a perimeter
frame around that foam panel to hold it in place. It has to carry a good
bit of cantilevered weight and movement in a concentrated small spot.
[Not trying to scare you off of it, just pointing out an important consideration.]
'Just throwing out one or two possible ways to do it for consideration.
