I am looking at buying a 24 foot Lowe Pontoon barge. It is in excellent shape as far as how it looks. Upholstry is great, carpet also. All guages seem to work fine. It needs the running lights worked on a little. The canopy is whole with no holes. I saw it in the water and have not seen it on the trailer. It has been either in a boat house or in a shop it's whole life except while running The Lake. What I need to know is, what else do I need to check? He is asking 8700 but would take less. I thought of offering him 7500 cash. What do yall think?
