This is an interesting example of perspective - if I had access to 30 pine trees an hour away I'd have the truck fired up first thing on the weekend. But given your situation, I think I'd maybe grab the larger trailer, take one load on the way home from your visit (it'll cost ya gas to go visit anyway), if you've got help the cutting and loading should go quick if you do it in 8' logs or so, then buck it at home on your own time. You'd have some wood, only one trip of gas that you're spending anyway, and the cutting and splitting effort you'd have to make regardless of what wood it is.
