I briefly had a RRS that I was planning to build into a dedicated trail rig. A few people here have built out RRSs; Esten and Chad. Esten's is a later one, and likely the one you saw at the Annual. Mario's minty green one was there, too, and I think I remember discussing it with you. They are pretty trail-capable out of the box, just like all the modern LR3 and later Rovers. The shorter wheelbase makes it pretty maneuverable, compared to my LR3. If you wanted a fun on the pavement but can handle itself off-road truck, the RRS is a very good platform. Some of the 2010+ ones have a rear locking diff, but it's harder to find. The limitation for adding off-road bits are two major things; brake size and parts availability. Wheel sizes are limited by the brakes, and all over the place. The 2006-09 4.4l NA motor will take LR3 18" wheels, no problem. I forget the specifics about the 4.2l supercharged and can't remember if any 18" rims will fit over the Brembos. 2010+ non-supercharged will take 18" compomotive wheels, and maybe tuffant wheels, or 18" LR3 wheels with spacers. On 2010+ supercharged RRS, I think you're stuck with 20" wheels. There are pretty good 20" AT tires now but you definitely will have a lot less sidewall. Depends on what you want to do with the truck, but something to consider. The bigger issue I had was parts availability. Off road parts for the LR3 are plentiful, tested, and all across the price spectrum. For the Sport, there aren't many aftermarket parts suppliers, so things like sliders, bumpers and roof racks can be way more expensive with fewer options. But, they're out there. I really like the RRS, and don't think you'd regret it. 510hp sounds like a blast (and is on my short list for the next truck I get). The LR3/LR4 is a bit more practical (bigger, more utilitarian design, etc) but the RRS looks better and is a bit more luxurious. There's a tradeoff either way, and no wrong answer.
