Yeah....rv repairs...rv dealers...mobile mechanics.
Personal recomendations go a long way in the rv industry...if you don't know someone..I am sure someone in your neighborhood has an rv....start a conversation and see if they would recommend one.
Personally I am a fan of an independant third party opinion. If this is a private seller...do not use their mechanic....find another locally.
Rexhall Aerbus XL 2900
Probably never going to have a chance to "drive" a Boeing, so I bought an Aerbus!
