As you can see there are lots of Journey/ Meridian owners on here, but if you have $20k to swap engines on a whim, then perhaps you need to move up the food chain a tad.
Neither of these coaches came with anything stronger than a 300 HP ISB in Cummins land, anything above that was a C-7. I have done all the mods Maverick has done and considerably more, as well as currently waiting for a quote from the local shop to re-clear the coach since CDI apparently has no idea what they are doing, and WBGO doesn't seem to care either. That's a big investment, but we like the layout and all the mods, so this needs to be done. It's not a Beaver, but for the price it's a nice coach.
