Fuel tanks

we have 2021 Raptor 423 Toyhauler. We are not sure which fuel tank is for the generator and which fuel tank is for the toys. Could anyone help us determine what the front fuel tank is for and the rear fuel tank? They are not labeled nor anything in the Raptor 423 manual. Thank you.

i would think the tank furthest forward would be for the gen and the rearmost tank for the toys..can you see where the hose or pump hooks up underneath? it should go to the toy tank

"AS A RULE" the front tank is the gen tank and the rear is for toys. I would fill both ( if you can afford it ) and then run the gen, checking the gauge.

Thank you. We cannot see underneath. We have a sealed bottom

The other option is to fill one tank and see which gauge moves

Yup, that would work. Now that I think about it, one gauge will move but I don’t believe the gauges are labeled. You’ll still have to use some and see which gauge moves.

Another easy method:

Fill both 1/2 way. Start pump and start transferring fuel. The toy tank gauge will go down and the Gen tank gauge will go up. If it doesn’t change then thats the toy tank

I'm not sure about the Raptors, but on the Fuzions there are two gauges. The generator gauge can only be viewed via inCommand and the Aux fuel tank has a physical gauge outside at the fuel station.

"AS A RULE" there are no rules in Keystone. My back tank is on the generator and the front one is for Toys. Makes no sense to me, seems backwards to me, but everything about my fusion seems to be backwards and makes no sense.
