I have an Amerideck XL for sale. I come to Colorado every 2 weeks, Gydrolic sled deck check out there web site to see it. mine is 100% line'x. will last a life time. selling cuz i bought a mega cab short box
Egesledder on here sells some nice decks too... don't count out steel, a well made one isn't heavier than aluminum, and will hold up very well. Obviously they don't retract... but that may not be as big a deal when you're looking at a price tag that's $1000 less!
One thing in general about decks... imo, stick to box frame decks, much easier to get in & out, easier to handle (you can load or unload alone, I do all the time) and they're just stronger, so they'll last longer. Ones with legs like the full lotus sway like a belly dancer very quickly.
Shoot me a pm if you're interested, happy to help.
I've got my current deck I'd be willing to sell if you need it QUICK too...
