Howdy all, I am in the process of bying a 20' Cobra Salem (1993) travel trailer tandem axle. Comes with AC, awning etc. in very clean condition. However, I was unable to check wether everything is in good working order, since the unit is winterized and sits outside. Also since the Cobra company is no longer in business, I wonder wether it would have any affect on future (?) parts/repairs etc. The sale price is $6200.00 US. Any suggestions or opinions is very much appreciated. Thank you. Frank PS: I am new to rv'ing.
