By far the best decks we have used or seen are Silver Lake Manugacturing decks - Motomikey's! These are the offical deck of the Extreme Team Riders. The features of these decks are awesome. The construction / welding can't be beat, the bracing under the deck allows for lots of room for storage in the bed of the truck - after running this deck all winter and the 1000's of miles of harsh use we put them through they still look brand new.
I run the bobtail deck and love it. The 2 piece ramp (short box truck) works great and is easy to handle even for 1 guy. The deck is also fully lighted with running lights and is the lightest deck I have personally run.
Another in our group runs the model with the extendable sides and it is an amazing deck. When he isnt hauling his sled he just slides the sides in, they have worked flawless all winter - even with all the snow and ice on them - I have been very impressed!
Another note, Motomikey (Mike) is one of the best with customers, he treats people great, stands behind his products and has excellent prices. You won't find a better guy!
Give him a shout on here, he will be straight up with you and treat you right.
