Looked at a 1989 ROADTREK 190 318 v8 and when we took it for a ride it seemed rather sluggish trying to get it up and running with the pedal to the metal on the highway. The van has all we want but we need to know if it will pull a trailer with 2 motorcycles on it up the mountains on 75? It travelled extensively and has 100000 m but has sat for the past 2 years except for short city runs and wonder if new gas, spark plugs, oil change, etc. will help this sluggishness ? Thanks for any help SEWRIGHT@MNSI.NET newbie
