The OP didn't state which he was able to purchase so there's a variable in there which need to be accounted for.....?
90% or so of the sides are finished. Some are rough cut, but still 3/4", and not the standard rough cut 1" thickness.
There is also the length issue. A 12' board in the bed of a Ranger with a 6' box is a problem also.
Just be careful and remember Murphy's Law.
I did a test run with 11 boards. My 6' bed (plus tailgate) made it fit just right, with some ratchet straps. I'm sure there was a good amount of weight on the tailgate though, which would mean I'd be more interested in using a trailer next go around.
If you are amicable to rent a trailer, it may be smarter to rent a van. U-Haul has one day specials that are likely close to just what a trailer will cost you.
I didn't contemplate renting a van . . . I thought about renting an F-150 but the cost was too great to add any value over the trailer.
I checked rates on vans in my area, but the inside dimensions are only 9 feet long. In order to get the full 12' boards, I'd have to get a 14' box truck. That's $29.99 per day, plus $0.99 per mile. The 12' trailer is a flat $29.99 per day. I think I'd still be better off renting the trailer.
And how many pallets will it take to get the same amout of usable material as the Home Depot board?
Perhaps I wasn't clear. I buy it from a pallet and crate company. They make customized pallets, crates, and shipping containers. So they have piles of wood stacked up, of all kinds of lengths, for them to turn into pallets and crates. I buy the boards BEFORE they turn them into pallets, not after, and not the scraps and shorts. I would guess about 1/2 of a quarter or a third of the boards are split and/or warped significantly. I wouldn't turn it into furniture, but it's fine to put bees in :) Still MASSIVELY cheaper than HD prices, even considering the time it costs me to trim, shape, sand and/or glue.
