So I relocated my evap to the standard location. Used the Kilby kit. There's, oh, about 1-2mm between top of evap and bottom of tub. Anything but a perfect road (sadly, a less and less frequent occurence nowadays ) and "bap, bap, bap..." in the back cargo area. QUITE annoying. I am planning on taking the evap down and either attaching the soft side of velco tape to the evap or to the bottom of the tub to hopefully keep me sane. But before I do that, I thought I'd post up and see if anyone else has other/better recommendations to quell the rattling. Thanks!
