yes I installed one on other side,much easier to get out on than the pull down type.
both types by AQUA PERFORMANCE.they also come in different lengths.
Be aware fuel not always available at dangling rope.year before last we were there and the generator was down for 3 days.people were camped on docks waiting for fuel.still a great trip.one bad thing all the ice cream and ice melted.
just a thought how deep is this "vault" you could have some grade issues trying to gravity out of it,also deep vault=deep trenches=more digging,if your soil conditions are anything like most havasu material the "ditch witch"type trenchers don't usually fair well
I know the feeling.Just sold our ocean boat last week,had built for us in 2003 know we're gonna miss it but we just weren't using it enough.
