Did I Make a Mistake Going to Single Gas Tank???

OK, if you read my introduction thread you know I had to replace a gas tank in my 73 Winnie. Both of them were bad so the mechanic removed them both. The one had a hole in it and the other just didn't work. Could have been the fuel selector switch, valve or the combo of both. None the less, he removed both tanks. 1 30 and 1 40 gal tank. He installed 1 50 gal ploy tank. He moddied it up and re piped the generator lines and fuel lines. It looks good. I'm now wondering if I should have put back what was removed. I know it's only 20 gals but then again it's 20 gal. Have any of you folks went from a dual to a single? If so, what size tank did you install? If the same size or smaller do you notice a major difference in the distance traveled? I haven't had this on the road other then bringing it home so I won't have something to test it against. I'm still concern as I plan to run the generator most of the time underway and at primitive sites.  There is lots of room under the coach so I'm thinking of installing a separate tank just for the generator. Have any of you folks done this???

poppatello - your answer depends on how much travelling you are going to do with your Winnie - those big block  engines are thirsty so that's why the second reserve tank - having a main tank and a reserve and having the generator connected to the vehicle gas tank was done that way so you could enjoy many miles before having to fill up again - also the generator  line is placed above the bottom of the tank  (unlike the engine fuel line that's close to the bottom) so that the generator does not run the tank empty and if the gen runs out of fuel you still have enough in the tank  to get you to the gas station -did your mechanic plumb it this way?   whatever you decide make sure this is done unless you install a tank for the generator only -  if you read through several posts here you will get an idea of what kind of  mileage these rigs get -  almost every class A  RV needs a big block series engine ( Dodge 440, Chev 454, Ford 460 etc in the older RV's) because of the weight  of the RV -  you need torque to move those RV's since you are moving not only the vehicle weight but also the house part as well - so its a personal choice -if you intend to do a lot of travelling then consider reinstalling the second tank.     Hm?

As Mike says, it depens on your preferences.  Me, I like to take a break from driving after a couple hundred miles.  So, just keeping the large tank for the engine (in my case, over 35 gallons) is fine for me.  The second tank (20 gallons) would be ideal to run a generator for quite some time.

As long as your gas gauge works perfectly, and as long as you become familiar with how many miles you can drive on a tankful before refilling...just in case your gauge stops working, then one tank is fine.  I like having 2 tanks in case of gauge inaccuracies, plus we do long trips all the time so having 90 gallons onboard is great.  And we use our generator a lot, so again, its nice to know there is a full tank in the back when we pull in for the night...but as long as your gauge works and you familiarize yourself with your gas mileage and range...you should get around 7mpg, but check!...then one tank will be fine.
