sewingcybermom, we've probably - no, definitely - have given you more ogeda than necessary. Fact of the matter, you can't plan and prepare for everything! If we try to do that, there's no fun and fodder for the campfire tales!
My Alma mater had a slogan that embodied the educational culture there and fit my way of learning and life. I think it applies here: Learn by DUing! Once you get it home, stock it up with basics (not forgetting power protection, water pressure regulator, black tank treatment, chocks, a level and some planks or equivalent to level) and begin your new adventures, learn and adapt while in the mix, and be a happy camper in your big upgrade from PUP life!
