Head over to HENDERSONS LINEUP to see if KONI FSD shock absorbers and FF or RR anti-roll bars and track bars are available. Mohos are terrible about having steering wander. Correction of this will save more fuel than any single aero change (save a boat-tail).
Proper weighing to get tire presssure ideal is also necessary, See the BridGESTONE .PDF on how to weigh an RV. It comes to individual weights for each wheel/tire. The RV Safety Foundation also has info. Weigh with full fresh water, full propane and all gear aboard for long trip plus weight for pax. CAT Scale, nationwide.
At WOODALLS are plenty of discussions on getting Class C mohos to ride and track better than from factory. While the Chevrolet may be better than the Fords there is no room for slop. Work the mechanical baseline (as in alignments specs that may be a hair different than what is present, for example) to start from acquired numbers. Axle weights are good, tire weights are best. Pressure is then set from there. Best shocks and chassis/suspension changes can make a HUGE difference. A rested driver makes a more skilfull driver as the day goes on. I;ve wresteled mohos staring 40 years ago, and have to drive worn 18-wheelers. There is no substitute for a "tight" driver.
That, and trip planning. One already knows the likely range for a tank of fuel. Choose the fuel stop in directon of travel and close to highway entrance ramp, for example. The number of acceleration and deceleration events is key, here. Stops and turns are contraindicated. Plan this ahead of time. Etc. The moho gone through and tires at best pressure plus some planning will take a huge bite out of the fuel bill. Top speed of 58-62 mph as well. If you can learn what the average speed is, then you'll understand that a high travel speed is really counterproductive when it involves lane changes and extended accelerations. Doesn't same time, my friend.
Keep good records. All gallons and all miles. "Success" is
a percentage improvement to the annual average. The number itself is not so important.

AN OBD-II reader such as ULTRAGUAGE is also recommended. THe time you actually spend at travel speed is not as great as you may think. THe transitions are what count.
