Congrats on the newtoyou rig. Suggest you post your questions on the Tiffen Owner's forum, here on IRV2, and also consider going to a Tiffen rally somewhere. That was, you most likely can find someone knowledgeable about the systems, and show and tell you about them.
If you get make and model numbers of things like the furnace, A/C, gen, etc, you may be able to contact the manufacturers, or search online, for further info.
Make sure you check your tire pressures, that they are inflated properly for the weight of the loaded rig; examine tires closely for damage; change fluids and filters, etc. Hope you enjoy your new adventures.
