2011 Discovery 42A Fuel Tank Quantity Discrepancy
2nd owner of the MH (purchased in 2017). According to all promotional data, MH has 150 gal diesel fuel tank. After driving it over 20,000 miles, I am convinced it is only a 100 gal tank. The fuel gauge will react to low fuel based on distance travelled if starting with 100 gallons vice 150. I have contacted Spartan, they insist 150 gal tank is installed. To test my hypothesis, I once ran several miles (~60) with low fuel light on. It took almost 99 gallons to fill. That's the most I have ever been able to fill it. Has anyone experienced this? I guess the next step is for someone to physically check the gas tank to see if it is labeled for 100 or 150 gallons. The computer acts as if it is 150 gallons for range computations (~1,000 miles when full) but I have to use 500 miles for maximum distance between fillups. Not a big deal, but curious if this was even an option when built. Thanks!
