My Father's Day Present (to myself =)

[AJ_77]

Got this from EmilyB yesterday - many thanks to Deb and esp. to Trevor and Barry for their mighty acts of strength. 72x18x21" outside dimensions.



I like 2x4's...



Except when they cause ONE corner to dip slightly - the front right. I've got a couple of shims under the corner, but it hasn't taken out the twist in the frame (whatI think the problem is)... will a half-ton of water do it?? There's 1" of styrofoam as well.



Any suggestions at this point?
