Titan HD to pull it?
That would be a good question. Not sure.
Here is part of the problem with using a SxS to transport me, a guest hunter, and one or two camera guys. We have a ton of gear that we are hauling along when we leave the truck. And we carry a spare of most everything that we leave in the truck. If we ruin something while out that day, we only have to trot down to the trailhead to get a replacement, rather than drive all the way back to our base camp.
The SxS option creates some hurdles to that. First is dust. Dust kills cameras/sensors/lenses. Just a fact of the environment we deal in. Not sure a SxS is able to be "dust-free" enough to prevent this problem from being amplified.
Second is security of gear we leave in a SxS/truck when we leave the trailhead. Yeah, someone could easily break into my truck and sound the security alarm. But, that is not nearly inviting as some gear being left in the back bed of the SxS for all the world to see.
Last is roughness of ride and space to protect gear during that ride. The truck allows us to put a lot of stuff in the cab when driving terrible roads to trailheads. And, the seats and cab space allow us to put everything in soft-sided cases or on the seats to protect the equipment.
Again, another unique need that is not applicable to most other people. But, is a big part of why my truck has to serve as a quasi-SxS.
