I would guess the thinking is that the double cab long bed would have more of a chance to high center so they don't offer it, but that is just my armchair analysis of corporate Toyota's thought process.
You could opt for a sr5 double cab long bed, and get the 16in alloy wheels option, and then after they add the 08 to the suspension TSB you'd get the TRD suspension as part of the TSB, then all you're missing in the locker.
A couple additional things come to my mind as well. Along with the higher risk of high centering (hell, I did that with my SB before a lift so image an even longer wheelbase...) it's not as maneuverable on tight or narrow trails. Couple the larger turn radius with someone trying to use the locker in 4LO on some hairy trail and it might be like trying to turn the Titanic!
Not that people couldn't use it properly, but Toyota might not want the risk of some, uhhhh, "less informed" people using it, trashing the truck, and suing them over it.
What do you plan on hauling anyway (besides firewood)? An ATV or bike? That's the only thing I can think of quickly where the extra foot would help. Most lumber is at least 8ft long in standard lengths so that will hang off the tailgate of either truck. (I've loaded my SB up with wood, and wood pellets.)
Something to keep in mind is the DC LB actually has 85lbs LESS load capacity than a DC SB 6spd. So for that extra foot in length, you're not getting an increase in weight capacity. So if you stack the wood right, you can technically carry more in a SB.
Now, if the LB had, say, 200-300lbs more capacity I'd say go for it! But you want off road options, sounds like the locker might be more useful, and you want to carry a bit of weight it seems. The locker would probably be more useful on muddy logging roads or forest trails if that's where you get wood.
Let me explain it this way. With the LB's extra foot I'd be able to cram the last 10 or so bags of pellets (40lbs each) in the truck because there is room for them. However, based on the weight capacity I should put in 2 bags less than the SB can carry. So it's easier to overload the truck with the LB.
