2417 Questions

Now that I think we've decided on the 2417, I have a few questions:
How big is the outside storage and is it one or two sections?
Is there storage under the dining seats?
Is there much storage under the sink?
Any bathroom storage?
Does the shower curtain wrap all the way around on the inside?
How wide is the countertop next to the sink?
How deep are the overhead cabinets?

Thanks so much for your help. The nearest TM dealer with a 2417 is 7 hours away, so I've only been able to look at the TMs online.
