Although i did see something that is really interesting I beleive that there is a company in the states that makes them i think thier name is diamondback or sumthing or other ( if you want ill find it again for you theres a guy selling one up here for $1800 CAD and open to offers probably. What it is is basically like the big boys you always see with the rack uptop the box has awesome tie downs and special cups on the front so you don't smash the windows on the back of your cab etc etc and the nicest part is it folds up from the back of the tailgate (half way) like a tonneau cover
. Then from the front of the box to the middle also opens like a tonneau cover again (50/50) i mean if you really want it on your truck thats the way to go. However i still would rather have a trailer personally. I just had this discussion with a friend of mine and i mean up here you see those decks above the box on dodge 3/4 tons and 1 tons single not dually although you do see those too. but they run like two sleds or two quads and even though this deck for tacomas only puts one up i mean tacomas are somewhere between 1/4 and 1/2 tons... do you really wanna risk the extra tippyness however my buddy brought up a valid point that if you had the right setup with suspension and airbags it should be fine
Take a look at this link : its in calgary alberta canada
I mean i saw this and was like WHOA thats pretty sick, but i mean for even $1800 i can get a pretty nice trailer and to all sorts of things with it besides atv holder. Although like the ad says it would be nice to have that uptop and keep your gear clean.
Just thought this could help in your travels
