Ours has a pair of 100 gallon tanks. I prefer them full, helps it ride better Filling the gray quickly does suck so we still do everything as if we have limited fresh.
same here. 106 fresh, 65 grey, and 45 black. have never even come close to filling the black but have filled the grey twice now. once, 4 day trip camping at the beach. the other time was in the desert so i just dug a trench away from the trailer and drained off a few gallons. washing 4 people (we do the navy shower- spray yourself down, shut water off, soap up, spray down) for 4 nights plus dishes... yeah its possible to fill the grey.
We don't use it to that capacity often. Usually only for boondocking when it's all 4 of us (me, wife, and 2 kids). Most typical camp sites at least have a hose hookup. However, it really does open up a lot of destination options for remote camp sites for more than a few days without risking running out of water or having to carry around a portable grey/black reserve tank.
Dirty sink water might as well just collect in a tub in the sink or... Get creative and put a valve at the bottom of the trap, dumping into a jug. Take the jug to the rest room or dump in the weeds, etc. Grey water is not a big deal (not illegal) to trickle drain thru a hose stuck into the ground. Cut ya an angle or two on some pipe/tube, "drill" into the ground about three feet, insert tail end of 10-15' grey water garden hose from tank discharge chute. Do not forget to have some way of distinguishing your grey water hoses, jugs, etc. as such. You don't want to accidentally use them for fresh water.
Sure, that's good anywhere, I was stuck at the letting it trickle out Although I have done so with a hose straight to a sewer grate....
Trickles into a three foot deep hole, not supposed to let it flow out of the hole, but I can see that approach isn't exactly track friendly with high foot traffic. I wouldn't do it at the track, either. Just a way to keep from topping off grey tanks when boondocking/dry camping.
So I guess my next question is, what is a great generator that will run the toy hauler with all the warmers and stuff plugged in?
I picked up a Northern Tool 3500 inverter when I got my RV 2 months ago. Same as the Harbor Freight predator 3500 but Nothern's standard warranty is better. I have 55 hours on it and it is fantastic! $700 and quiet as any Honda/Yamaha. Unless you have multiple warmer sets going and an A/C it should take care of everything for you. If I ever need more power I'll get a second one and connect them, still be 2/3 the price of a Honda 3000.
I run my travel trailer (with AC) and tire warmers no problem with two of these in tandem. They are super quiet and you can control and monitor them with your cellphone via bluetooth. https://www.homedepot.com/p/RYOBI-B...OMIxIDloHsuhYEDM99RoCsqcQAvD_BwE&gclsrc=aw.ds
