I've had the LoadWarrior for about 5 years on a couple of different 4x4s, but recently switched to a Thule M.O.A.B. basket...it's not called the PlayPen anymore...they changed that about a year or so ago...maybe more. No, they're not the same company...but a lot of their accessories and mounts work together...for example, my Thule M.O.A.B. mounted up perfectly to the Yakima crossbars....the shovel/axe mount "almost" fit the M.O.A.B. I had to "tweak" it a little to get it to work...otherwise, yes, you can use many other Yakima bike and ski/snowboard accessories with the Thule baskets with no issue. I like the looks of the Thule basket better, and the basket is a little deeper as well.

Here are some shots of the Thule basket on my Xterra:
