Below you will find a quote of a response that Scott made to my question of the possibility of customizing a trailer with an instant-on hot water heater, a full trailer water filter and either installing for me, or allowing me to install my own refrigerator.
I hate to do this to you, but I am going to have to give you the big "maybe" when it comes to giving you a definitive answer as to what we will be able to do on our production line. I will have to speak to my partner John who is the engineer about the water heater and the water filter. If they will fit in the areas already provided, I would say the possibilities are greater. As for the refer, the only thing I would say is that we could possibly leave the space there for you by taking the cabinetry out and let you install your own refer. It should fit through our larger entry door, but we would need more details.
