The above link will give you pertinent info on PODS. We used one POD in our move from the Boston Ma area to The Villages. At that time I believe they only offered the 16 foot length for long distance moves. Now looks like they offer a 7 foot also. From the OP dialogue, terms like several trunk loads and use of mail, it would seem that a POD would be overkill.
Our experience was great. We sold much of the big stuff. Collected moving boxes, packed them ourselves , moved them to the garage. As we closed in on moving day, we had POD delivered and leisurely loaded as we had 30 days to load. House gradually emptied down to bare essentials which we loaded on last day.
POD delivered as scheduled and we unloaded at our pace. Since essentials were loaded last, they came out first . Even with our plan, we still brought too much.
