I wouldn't have purchased our LR4 without it. We do take our truck off road quite a bit. I have too many times watched a truck struggle with a steep slippery hill as one rear tire will spin faster than the other and the truck will have to attempt the hill multiple times or be winched up in some cases. The dealer did have to locate the vehicle and we ended up with the Lux package when all we really wanted was the HSE. but I can't tell you how many times someone watches me take a difficult hill and comments how easy I make it look (and it's not me it's the truck) The HD package will turn your truck into a vehicle that can truly go anywhere the only other mods I made to our truck were Johnson Rods (lift kit) and Pirelli ATR All-Terrain tires. If you're not going off road why get a Land Rover, and if you are the HD package will allow you to do things that will make other peoples Jaw drop as it locks up on a hill and climbs hills that look too steep and too slippery with ease.
