Our ONLY experience with that place was to pull in, badly in need of a dump station and they directed us to an open site. We went to where we were told and stupidly began to dump, before we were told the dump fee was $25.00.I told them that was ridiculous and stopped the flow. When we could not get anywhere with a reduced rate, I opened up the dump valve and when we were finished I paid the $25.00 fee but have never been back. We go to The Road Runner Park on the Airport road and pay $5.00 plus tax. Comes to $5.36 to dump and they are very helpful and friendly.
Put coach in Reverse with emergency brake released and take foot of air brakes to allow drive shaft to turn and break rust locking the brake. Your four wheel brakes have not been on so no worry there.
This happens every once in a while if wet air or rain in area.
Post and let us know how you make out.
