It's the Erickson Big Bed Junior and has a rated capacity of 350 lbs. I hauled some pressure treated 4x4's and 4x6's in 12 and 16 foot lengths and had no issues. It doesn't fit snugly into the hitch receiver so it wobbles a little but didn't seem to cause problems. I've also used it vertically to haul things with the roof rails & cross bars and that also worked well, aside from the wobble.What length of lumber can that extender handle and any idea of weight capacity? Need some of 16' cedar siding, woodpeckers are getting hungry up here
Here is a link to the exact product I purchased from one of the big box stores for about $70. Price has gone up significantly since then:
