We just made our first 500 some mile round trip.Dry camped for a few days at some sprint car races.we got a little over 10mpg on the way there,Dash AC 1/2 of the way till dark.Great run getting there and spending time with good friends.Well on the way back
halfway across alligator alley,My main tank was a little over a quarter and I am thinking
the aux is at least at half,Well its showing below empty!!!Panic starts to set in when I start running out of gas,I flip to aux to engage the electric pusher pump,even though it showing below empty it kicks it back to running good.I switch back to main and all is good for about a mile then I run out of gas again,switch and go and switch back.I flipped that switch back and forth Freaking out the whole time,for about 20 miles.We made it to the gas station but sheeze it was too close.Now standard is never let it go below half!!The manual says stay on the main till empty then go to Aux.It seems it fills both and draws both no matter what.

I do have to say,we did have some small issues that could have been Catosrophic.For example.Hit the water pump and I got a sprinkler under the stove.Not too,Too bad to fix,a few bucks and twisted back.Original Buzz box dies,unbeknownst to me,KILLS front and back batteries.I carry a charger,and jumper cables so....Hook up to a water hose,utilizing my pressure regulator and another sprinkler behind the closet,more twisted back but fixed.Brake pedal goes to the floor,Red Light no brakes!The cover was a little distorted and brake fluid was blowin out the side,Again no real big whoop!Try startin genny and short in one of the rockers and the starter Stays engaged after it fire up.Just replaced all the mounts and broke bracket.Sprayed contact cleaner at all locations,refire and ok.Then,Half hour later,gen starts surging and Dies! Totally clogged and Filthy in the bottom of the bowl and the air filter,I don't even want to say.
The very 1st Toll Plaza. I have to pay,pay,pay cause I got 2 extra f-ing wheels.
VAPOR LOCK.....Stalls right out whilst trying to blend in traffic.The coolest thing was
how actually far,far,far we coasted and how hard and firm the brakes were without the motor running.
My wife and I just got out walked around in circles for a moment,got back in till we really ran totally out of gas!!!I feel we drove about 22 miles on absolute FUMES.I was switching that switch every time it stumbled, Everything about the whole trip was awesome...She said gee its kinda like your car,Nothing will stop it!!

My driving rule for the GMC; Stop every 250 miles and fill up the tanks. I can empty mine and refill the GMC at one time.

Anthony,
First - Get to Know Your coach!
* Calculate the fuel rate (MPG) on every fill.
* Make notes as to weather, terrain and APU run time.
* It may take four or five fills for a fuel rate to stabilize.
The fuel tank setup in the TZEs is indeed strange, but it can be managed effectively with some thought.
Points to remember:
1 - Then tanks are joined at roughly half the volume. (The main tank easily spills into the auxiliary, but not the other way.)
2 - The APU (genset) fuel pickup is in the main (rear) tank and only works with that tank above one quarter.
3 - The gauges on the panel are nearly worthless. (They are trying to read the level in a six inch deep thank that is three feet by four feet in plan view. - Read No Way) And, the low fuel warning light reads the gauges.
So, if you run down the fuel to about half and then switch to the auxiliary tank, you will still have about 10~12 gallons in the main. That gives you six hours of APU run and still about 50(+/-) miles of range.
Can the fuel inventory be effectively managed?
Yes, but it takes conscientious and careful doing. I always write the mileage on the fuel receipt and the Eoh content. (My coach does about 9+ on craphol and 10+ on real gas.) Several times I have pulled into a fuel stop and put 53 gallons on. And, yes, that was intentional.

I spent $225.00 and we drove 514 miles and I ran the genny after I got it running good for AC for about 4 hours.Then another $50 to get home.$3.81 per gallon on the fill to get there $100.then 3.89 for the $125.That last $50 was emergency rest stop price of $4.11.I figure about 10 mpg.I did have dash AC at Max 1/2 way there and 1/2 way home.I am ready to go out again next weekend,maybe to Key Largo?
