I have my boat at Alotta Storage in Blythe also. Currently paying $160 for the 30ft enclosed unit. When I signed up last year, he gave me 20% off for the 1st 6 months, so it was only $120 until Nov or Dec.
I also had my toyhauler there in an covered outside spot. $70 a month, and same 20% discount at first so started at $50.
its a pretty nice place and I feel like my stuff is safe, but i still put a couple locks on everything just in case. And everything is INSURED!
