welcome to the group RV Gal,, First as to your quesions of sinks, its a matter of personal preference but for me it was not a priority, I use paper plates and my clean up is minimal,,I use the plastic wash tub wash and rince method and I save the space for something else like a coffee pot,,now we talking a real priority,,
next on your question on cabinets in the galley,,I would love to have really beautiful ones in the ggalley but alas

I am not a cabinet builder,, therefore I opted for pull out baskets on a shelf, they actually work very good, when I am getting ready to go camping I pull 4 out on the kitchen cabinet and put in or pull out what I need for that trip, slide them back in and I am done, if you look at the shot of my tear on the hall of fame you can see the rear shot with baskets and also a/c in the top middle of the galley,
ok now get busy and join us at a gathering,,
