[QUOTE=rspears;454387]Mike,Not sure what your trunk lip area looks like on the Gibbon body, but on mine it forms a "trough" across the back that is about an inch wide & an inch deep, rounded a the bottom - can hold a LOT of water /QUOTE]

I had found that also on the project33 website! I still need to do mine! I have the parts/pieces, just need to do it!
