VOLVO, FORD, MACK

I've been doing looking round at a couple older tractors and I've ran across a couple trucks that I would like to know more about can anybody tell me somethings about these trucks good and bad, various motor/transmission builds , mpg , tractor setups all advice and info would be appreciated

1. 1995 Volvo WIA
2. 1985-1990 Ford LTL
3.1989 mack superliner

 

Thanks a lot the superliners are hard to find and I'm leaning on the Volvo more because there more commonly found and I would either be pulling containers or hauling logs

 

Thanks a lot for the feedback I ran into a guy today that has a LTL9000 He said he has had it for about 9 Years and hauling logs with it he says it has a CAT 3406 With a 9 speed
