Death Valley test
Just returned from a week long trip to Death Valley. Other than a small hiccup before we left (small amount of gas escaped via vent tube, entered charcoal filter and set off engine warning light---easy fix by installing a longer tube with a loop. No issues on 2K trip to DV and back to Bend) it was wicked great to have 40 gal tank. With Adventure trailer in tow, and especially off road on class 2 & 3 routes, gas mileage sucks. With 40 gallons there was no worry and no need to buy $6 a gallon gas at Furnace Creek (OK, actually "only" $5.85 for regular...ouch).
Most of time was spent traveling over the Mengal pass via Warm Springs Road (from the valley side). Because the additional weight is so low and almost on center line (front to back) I never could feel any difference in handling. My front end Bud built skip plates took some slight blows in short class 3 section at the top of Mengal pass, but not a scratch on the gas tank skid plate.
I cannot say enough about the quality of the build and install. When we encountered the warning light issue Shane at Custom Exhaust was on it, quickly figured out what had happened and did the fix for no charge.
All in all the tank addition was all I had hoped for. Next trip is White Rim Trail before the Expo in Flagstaff.
