We love our Georgetown! It wasn't instant love, as we transitioned from a 5th wheel, which is the best space for the money, but I am convinced now that we made a good decision in switching to a motorhome. We love the living space and kitchen in the 378. There's actually kitchen counter space!! The 2013 has the new residential refrigerator (electric only) which is huge and awesome and serves as extra storage space for dry goods that won't fit in the cupboards.
We went with the linoleum option throughout the coach so much less carpet to clean. We also like the drapes, though I've heard others complain about them. I like that there are no blinds over the dining table--the blinds are so stiff and hard to use. I'll be curious to know what you end up doing with the dining table. It's a little awkward having a dining table on a slide, especially as you move chairs around and they get unlevel. We're thinking of turning the table sideways (long ways to the window) and putting both chairs on the long side facing the TV. Don't like the chairs--rounded backs make them hard to pick up and move, and in a small space you need the corners on square-backed chairs to hang hats, coats, etc.
LOVE the fireplace. It got down into the 20s where we were camping last month, and the fireplace provides a steady source of heat which nicely complimented the off/on thermostatically controlled furnace.
The bedroom/bath area is a little tight compared to what we were used to in the 5th wheel, but it's worth it to have a readily available bathroom while traveling. We make much better travel time since we don't have to stop (for me) as often! Hate the bedroom door--it's always in the way. And the coach is hard to level perfectly enough to keep either the bedroom door or bathroom door from falling shut or open. So I've taken the bedroom door off and will use a tension rod and curtain for now--maybe look at an accordian door as a future option, but with a 24 inch opening, that may not be practical.
We added a paper towel holder, toilet paper holder, and towel ring between medicine cabinet and shower. Also a couple hooks to hang coats on just behind both front seats. We live in ours parttime, so it's important to me for it to be as residential as possible.
Let me know how you like yours and any modifications you may make. Probably good to take a maiden voyage before making too many changes. I thought I would hate the drapes, but I like them! I knew I wouldn't like the bedroom door but decided to travel once with it before making the decision to take it down.
