I'm gettin too old to spend all my time maintainin' vehicles, so I'm thinking of lettin' my '89 go and selling my Buick and gettin a 98 quad cab. I've still got the brand new 12cm turbo that I haven't yet installed. Any advice on pickin a 98? Should I save the turbo and put it on the 98? Other than the turbo, is there anything else I can do to it to make it more efficient? Can I expe3ct considerably better fuel economy with the 98? Would a 3/4 ton have any problem carrying my 3000 pound Lance slide-in? I figure you're the obvious person to ask these questions.
