First time RVers! There will be two of us, possibly a third some of the time. We would hope to use our own bathroom at night, but mostly use other facilities during the day. We are flying there, and an RV will be delivered to the site for us.2013 Crossroads Z-1 25' is the leading option so far, and it seems great, but apparently it only has 26 gallons of black water storage. There's electricity, but no way to dump the tank for 11 days. Any guesses or advice on roughly how many flushes that would be? How many days that would last? How many gallons of black water storage should we have, if we plan to last 11 days? Also, we will be given a regular 110-120v household extension cord to plug into, which is hooked to a bank of generators for the event. But I wouldn't want to try to draw a dangerous amount of power. Any advice on using a household connection like that?I checked the FAQs and read a lot, but still don't know for sure about these two issues. :) Any other advice about this you may have would be great!

You could fill the 26 gallon black take in three or four days. If your only peeing at night it should last fine. How about fresh water? A 20A extension cord? You will run nothing except lights, charge battery and the refer. Water heater will need to be on gas.

If this is at an event I'm sure they will have a honey bucket service that can pump out your tanks and some times will have water trucks that will sell you water.

Family of 4 can go 2 weeks almost without dumping. But at that 11-12 day period the tank was at its limit.You will be limited by the fresh water tank anyway unless you can fill it somehow.Grey is always often the issue. But my fresh water matches the grey tank size of 50 gallons. Si I never have any issues. Usually when I run out of fresh water I can fill the fresh again. Your best off using the facilities when you can.As far as the 120 pigtail you can run anything but one at a time. Run fridge on propane if your running the a/c. Turn off a/c if you want to run microwave... As well as stated WH on gas. Ect .Youll just trip the breaker on generator if you overload.

Reading all your replies and I appreciate them all!The fresh water tank is apparently 40 gallons.There is definitely no pump/dump service at the event. Very unfortunate...Re the power, blowing the breaker on the generator is definitely not something we want to do to anyone else trying to use it. I looked and found plenty of 30 amp female to 15 amp male connectors, but nothing with its own breaker that would help prevent that. Maybe there is not a good solution :)Still figuring it all out!

How long will 26 gallons last? (Also, a power question.)
