Update: I got the 15" Sendel wheels from RecStuff to go with the new Carlisles. Got the LR E from Wal Mart for $67. 4 were made in May, 1 in June, so all 5 are 3 months old or newer. Took them home and installed them this afternoon. I Should be set for a while now. Ready to roll em next weekend and try em out!
