Hi and welcome to IRV2. In addition to this great forum, you will find extensive information on "Trek Tracks". The forum for Safari Trek owners. No cost to join, but you do have to register. Highly recommended!
1998 Treks came with gas or diesel engines. The Chevrolet Vortec gas engine is 7.4 Liters. The Turbo Diesel is 6.5 (Chevrolet had a 6.2L non-turbo earlier but this wasn't used in Treks). Pathmaker is an accessory package. Our current Trek has the gas 7.4, and we tow a car trailer with overall weight of 5000lb. This slows us down on hills, but is easily drive-able. Without the trailer, we don't slow down as much, but you can't drive these things like a car.
We find the "Magic Bed" useful. There is a wealth of bed information on Trek Tracks.
