Oshkosh Frame Trek 3060

Post by Jdviescad »

I'm looking for any information on fuel capacity (Fuel Tank size). I have a 1994/95 Safari Trek 3060, I'm pretty sure it's on a 1993 30' Oshkosh frame. it's one of the odd ball Treks with the 5.9 Cummins on an Oshkosh frame. I/m kinda assume it's very similar if not the same as a 1993/94 Sarengti/Kalahari. any info on water and holding tanks would be great as well. question on start-up, when I turn on the key, I hear what sounds like the fuel pump or some other pump turn on, but no light on dash for glow plug or alarm sound? I have no manuals or specs on our coach at all. I belong to the TrekTrax group as well, but having an oddball I can only get the very basics and mostly a guess. thanks any info on this would help a bunch.

What you likely hear is the 12V vacuum pump building the vacuum, used for the operation of the in dash heater AND/OR the 12V air compressor building the compressed air necessary for the operation of the air horns and exhaust brake... (if so quipped).

Thanks for the info. This 3060 is a pusher in the basic way. It’s an older 12 valve 5.9 Cummins with an Allison 542. No air brakes so no on board compressor. Leaf springs No air ride suspension. 18,000lbs 12 on back 6 on front. 19.5” rims. And only 30ft. So an oddball for sure. One of the Safari experiments for the Trek line or a special order not sure. The closest thing I can find to it is a ‘93/94 short 30ft Sahara

Does "a pusher in the basic way" mean that your Trek has it's Cummins engine in the rear?

The Kalaharis were built on the Spartan chassis, when they were phased out, there where some Spartan chassis left. So they made a few franken Trek coaches. It is also possible that there might have been Oshkosh chassis left over from the pre '94 coaches that were also used up as franken Treks. In '94 SMC switched the Sahara, Serengeti, and Continental lines to their in-house built, Magnum chassis. A few years back, I actually saw a Trek with an 8.3L Cummins in it! Talk about great torque to weight ratio. :lol: Not quite as good of a ratio as the Panthers coaches with the big CAT C12 engines, but not that far behind.
