Well, one thing I learned from Liberty when I picked my Coach up was that my huge head had the retention capability of a sink sponge. Now knowing this, Liberty still proceeded to walk me thru all of the different systems and pointed out where everything is located. This eventurally worked out pretty well because when I called Liberty for Help, Troy would simply direct me to an area he had previously shown me and then instruct me what to reset, check, turn, flip, push, etc. So, you do not have to retain all the info , just the main systems.
