A sled deck is the ideal option - it does reduce the useablity of the box of the truck, unless you also buy a pull out drawer system for under the deck. The deck alone is about $2500-$3000 or there abouts, without the lower drawer system. I see lots of quads on sled decks around these parts, they are 8.5 feet wide so hold two quads side by side. The one for my truck would be 7 feet long (84") so my quad would just fit with an inch or two overhanding the back of the deck. Most come with a retractable ramp that slides up under the desk for transport. They can be side loaded but in this case rear load would make more sense. I can see us going to that option if my dearly beloved decides she wants to drive her own quad rather than taking turns driving the 2 up. Maybe next year.
