you guys all SUCK :):D
used to keep mine outside :( until last year after loto when I was unable to get the cover on it and left it out for 2 months and it faded :( was paying 97 a month for 2 parking spots longht enough to keep the truck hooked up to it. This was a a locked camera survalianced self storage. 6 am - 11pm access
what I did not like was being parked next to big motor homes and trucks. to close together.
this year I feel I lucked out and was able to get into a storage building for 1400 a year. my own door. nothing within 5 feet of either side of it. however, it is an open area building but iwth NO public use at all. I call them the open the door I hook up and go.
no place around here will do longer then 25' for rack storage.
and slips you have to BUY :( most that you can rent for my size are above 3 grand for the summer only

I am paying $55 a month for a 11x30 stall, enclosed, but not temp controled. It is 5 miles from the house, but an 1/8 mile from gas and ramp. Maybe I can get smaller stall for wife, and take boat home!:D :D
