Thought it would be hard for you to downsize. Is your son in-law going to build you a new one or are you looking at a new one with Shasta Lake Houseboat Sales?
We will have him build it,working on plans now we have access to a permit ,hope to have it done later next summer as he has a lot of boats to build.
this would be a good deal for a couple guys to buy and use at all the lakes,it costs a lot less than a regular houseboat or even a motor home ,you could finance for around $ 360.00 per month so it can be owned for less than what it cost to rent a houseboat on shasta a couple times. and it can sleep at least 8 people.
