Plan A:
My suggestion John would be load up and move to Florida...
Problem solved!! 300 days of fishing... give or take weather.
Most RV places on the water have dockage and storage.
Most of the people that stay on site have large tug vehicles,
make friends with one or two to let you borrow their truck to get
in and out!
Plan B:
Buy a 2 door speck that gets 40 MPG.. KIA, Civic or the like.
Leave the truck at the RV park for in and out at the ramp.
My neighbor that owns the property next to me comes up about
once a month from Palm Beach with his 1 ton Ford that costs
him $200 round trip. He has a travel trailer on his site which I
provide power and water to him from my barn.
He bought a mini beater car just for coming back and forth..
His last round trip fuel cost was 1 tank at $40.00
Hope it works out for you!
