Rick, I think that's a great idea considering your usage. I also have a 10' Alaskan NCO but mine is mounted on our truck. This way when we head out on longer trips the mileage isn't hurt by the extra drag of the trailer, and we can go where we want to without the hassle of a trailer.
In our case the truck will go anywhere with the camper that it can go without, within reason. OTOH, as you said, being able to leave the trailer/camper behind in a campsite and go wheeling would be a significant improvement. Many times we have wished we could do that. Let me elaborate: many times I would dearly love to leave the wife behind in the trailer !!
