TCW will be worth the drive. Even if your aren't interested in used, make sure to look at his used units too. One may jump out at you or give your other ideas to consider. When I was there a couple of years ago, I had the opportunity to look at some used units he was in the midst of resealing. Not only was he recaulking them, but a number of places they had pulled off the trim to also reseal. That is going beyond what he needed to do.
In regards to the loading/unloading on the softer ground, that shouldn't be a problem. However, if you do see the ground as being too soft, just throw some gravel in the ruts you create. It will eventually give a good base yet still allow the grass to grow through it for a nice looking area.
Storage is over rated to some degree as I think folks try to pack to much for the "what if" instead of learning to make do. However, you will need a certain amount to handle the winter and summer variety of clothing. Only you know how much you will need to carry so only you know how important the storage space is. But remember, more storage means more weight and it adds up faster than you think.
Lance, Artic Fox, Northern Lite are all up in the quality so picking any of those you won't go wrong. Even Bigfoot is a good choice if you can live with the missing 6" of bed length.
