You are probably going to have to travel to find the boat. See my Thataway Album, on putting on the roof top airconditioner. I have some more detailed photos of cutting the wood frame for the inside if you wish, PM me.
On the 22 or 25, probably the generator needs to go in a rack in the cockpit. I will be making one for my 25 and put photos up shortly. There is no problem with the gas--but CO--so the exhaust must be directed away from the boat.
