Make sure all the gauges work. They'll go over everything on your boat, including how to deal with the bimini.
I just hope they give you a full tank of gas. I'm still mad about my dealer putting in 5 gallons of gasoline, and trying to sell me an expensive set of ropes and new life preservers. I had my own ropes and ski vests with me--just in case.
And have an agreement that if the propeller's not performing correctly, they'll swap props for free. My engine was hitting the rev limiter @ 6300 rpm's with a 14 pitch prop, and my dealer had to order a Reliance 15 pitch (that is perfect.)
Phew! I'm glad I'm not the only one who thought sleeping on the boat the first night we got it was a good idea. My wife thought it was a little weird when I slept in mine in the driveway last night. Until around 4:45 am when it started raining at least.
I'm where you are waiting on a 37' fifth wheel trailer to come in.
But my diesel tow vehicle is in the shop for a cold start problem. I've still got to install a tranny cooler, custom fifth wheel hitch mountings and a rear air suspension. Then I've got to get my hot rod ECU reprogrammed for towing.
