How big is the fuel tank find out, write it down
Go fill tank up, now add the numbers how close does fillup + 20, come to the listed capacity of the tank ?
Go drive about 150 miles, fill tank back up, how many gallons
What mpg, did you get, where was the fuel gauge setting before you filled it
Did you use a quarter, a half, almost zero, did the fuel gauge move enough for the gallons used
The first thing I did when I got mine was, fill it up, and I knew the history of the coach, but you don't drive around with low fuel in a DP, especially if you don't how how the fuel gauge responds
Clogged up fuel filters, can stall you out
If this RV sat for sometime with partial fuel, the tank could have
Algae in it
Get some algacide treatment for it, pour it in there and fill the tank
And get some spare fuel filters and carry them
If you have algae you will most likely clog up again
You might want to get the tank pumped out and cleaned, now before filling
Somebody with more experience on that will post some advice
