To answer questions:
Yes, the bathroom door is just a shower curtain. We've been married 46 years and any modesty has long disappeared.
One EggCamper owner on this board did put in a "regular" door and said it was a pretty easy project. If I remember correctly, he bought a shower door at Lowes (etc.), and used it. Maybe a search will bring up the discussion.
Yes, the floor is resin (or fiberglass, I don't know the difference), coated wood - both top and bottom. There are drain holes in each corner of the camper for any condensation or leaking water to drain through. Right after buying the egg I did discover a leak around the emergency window, but it was an easy fix with butyl tape.
Yes, it's still available, as a matter of fact, we just had it out for two night this past week. I just finished a review of the park here:
Blue Angel Park - Perdido Bay, Florida
Oh, and the shelves are in the closet next to the door. I put in wood shelves in the top, and a set of removable wire shelves in the bottom. That way I could still access the power panel in needed.
If we still have the EggCamper this winter, we plan to attend "Scamp Camp" and visit relatives in Largo and Bonita Springs. I'll drop you a line some time before the trip if it's still a go.
