I had almost the same rig in a 2003 Journey. Nice solid rig. Mine averaged 8.3 mpg over the 40k miles I ran it, mostly our West, and it climbed the hills just fine.
Clean the radiator and the charge air cooler if you can get at it from inside. Simple Green in a sprayer or Dawn soap works well. That engine/rear radiator can overheat if it gets too full of crud. Make sure the oil "slobber tube" is exiting well below the radiator.
If you don't want to do it yourself, take it to a Freightliner or CAT shop.

One more thing: there is an enormous amount of info downloadable from Winnie's web site, including the full build specs and diagrams for your specific vehicle.

Even though I don't have a rear radiator of concern, I did make up a gator aid bottle with a bunch of holes drilled around the top and a little bit of steel wool in the bottom. Used a section of plastic plumbing and hung the bottle on the bottom of the slobber tube. Keeps any oil discharge from it, off the toad, but so far haven't collected much of anything, worth emptying.
I believe Cat makes their own sophisticated cure and expensive of course, for those who may want to go that route. Others have just hooked on to the tube and rerouted it around behind the radiator somewhere.
