RVTRKN
89 takes a trip through MT Carmel tunnel, we could have gone that way but somewhere the in the info said that they have to close the tunnel for one way traffic for oversized rigs and a $15.00 bill to do it. Today after we set up in the RV park we took a ride WITHOUT THE TRAILERS or MH, I think that with the height of the MH and the other two 5er's we would have to straddled the center line to do it.

Besides the wife likes to stop in Mona UT at a Lavender Farm to get oils and fragrance for her soaps.
Stayed the night in a Truck Stop (loves just North of Cedar City UT) actually very clean and fuel pumps looked as if somebody actually cleaned them I went to the fuel drop fills and lifted the lid, Dry & clean
I fueled the MH and received a FREE SHOWER TICKET which I promptly turned and suggested to the trucker behind me at the counter TO USE IT!!! Good Lord I've shoveled Crap and worked my Butt off around animals AND NEVER DID I EVER SMELL AS RIPE AS THIS GUY.
Almost 9 MPG fighting a mild head wind with the rig loaded as heavy as it will be with provisions and liquids so I'm pretty happy with that!! we were averaging 60/65 MPH.
The exhaust and or air cleaner made a difference of 125 degrees in the EGT. The difference in the exhaust was from 4" plumbing to 5" without the offset drum style OEM muffler to the Aero Turbine.
The air cleaner was one of the sealed type that the entire thing was changed when replaced, I went with a Donaldson with a removable filter. OEM was said to be 1100 CFM the new one I installed was 1300 CFM.
So don't know what one made the difference in the EGT but it ran really good.
Even was able to keep the windshield in place when the BIG BOYS come rumbling by. :-laf
