How big is the hot, cold and grey water tanks on this.
How do you lock up the canopy for overnight events?
We would take anything of value that was not built in and secure it in a pick up or another location. We have considered in closing the top with a tin walls and then putting the canopy over that. It would give the save Wagon look but add more security.
Is there room for a standard size refrigerator
Yes, if you cut a space out of the stainless steel counter.
Would you be able to put a grill and fryer in it?
It would take some retro fitting and it would need to be a smaller grill and fryer. But yes you could do it. There is a open ice well at the end of the wagon that can be removed that might be a good place for it. We used a small portable fryer in the wagon and a small portable grill that we set up under the canopy outside the wagon. I will try to add some picks of the well area that I'm talking about.
