I have an old Boler with a traditional fixed cord
. The cord compartment under the dinette is separated from the rest of the space by thin plywood panels so there is no issue with tangling with other stuff - I think that should be a standard feature of this sort of cord storage. It can still be a pain to push the cord in and pull it out. Not ideal.
Our big fifth-wheel trailer has a separate detachable cord
and an outside storage compartment which is convenient for it. This works well and avoids any pest entry issues, but it means hauling the whole cord out any time it is needed... and it's a 50-amp cord which is more than twice as heavy as the same length of 30-amp cord. Also not ideal.
My motorhome has the big heavy 50-amp cable, fixed. This would be ridiculous to stuff in a compartment through a little hole, but the fixed cord is in an outside accessible compartment
(in the "basement") - the cord goes out a small hatch, and can be (must be) wrangled by opening the door. This actually works pretty well, but it would be easier if the compartment door had a notch so it closed on the cord, after taking out only what is needed. I actually bought a conversion kit to make it detachable, but decided that it wouldn't really be an improvement in that particular RV's installation. I might still notch the compartment lip at the bottom of the door opening.
The slickest solution might be a cord on a reel
in a compartment with a door that could be closed on the cord. I've seen big Class A motorhomes and fifth-wheel trailers with power reels. That's pretty tall to fit in any Escape compartment, but could be mounted in a box on the rear bumper, or even in the front storage compartment.
A reasonable solution for an Escape might be to have a fixed cord in a compartment (presumably the stock location) with an outside hatch door and a notch in the edge of the door. The compartment would be dedicated to the cord (no tangling with anything else), sealed from the interior, and accessible for cord wrangling; the cord would be fixed (no expensive connectors, no easy theft) and all but the required amount could be left in the compartment. The notch needs a flap to close it when the cord is not out, as is common on small hatches for services.
