couple questions to ask yourself about it:
will you be in decent comfort driving the rig there and back compared to towing it?
will the added expense of towing hurt you that much?
will you be able to have the mind set while wheeling that you have to drive it home, some people can't and end up breaking big stuff regardless of the need to drive it home, and then sometime shit happens even when you are taking it easy...
I prefer to trailer for most any trip, but then my rig doesn't get that much different fuel economy over the tow rig. Knowing I'll get home broke or not is worth the extra expense to me, but as a few have said, it is definitely doable.
