Casa Escarlata Robles Too - my under the sink area has more of a lip than yours, I think, but I really like that roll out!
Hoyden. The basket it self sits on a frame that screws down and slides out about an 1" above the bottom.My opening is 9" with a 1/2" lip,so the basket slides over the lip.
Also our storage, mostly clothes are kept in the rear cab in file drawers,but we don't have animals with us.
Our other storage,caned food/all the food ingredients for our meals (that don't need refrigeration) are kept in another 2 drawer file at the right rear of the camper. Makes organizing everything easier.
Also storage in the rear dinette seat and the front where the battery is.Great place to keep a few bottles of our favorite wine.
Also we take full use of the turnbuckle access holes.
I have a side dinette and still have loads of room,as Bill D states try to take what you can't get along your trip.
We keep telling ourselves that "remember there are stores along the route".
Our basket contains pretty much what Bill D carries. 1 pasta type pot, 2 fry pans ,2 sauce pans. euro style espresso coffee pot,small "perk" style coffee pot (used to boil water). extra can of bear spray,1 pot lid,( the other 3 sit in a rack behind the sink,and last a 5" strainer with handle. It sounds like a lot but it all fits and is well organized. The under sink area has room left for the small bottles of OVOO,vinegar "Pam" spray,napkins,stuff like that.
Then 2 1/2 gallon bottles of water and another bottle of wine.
Sounds like a lot but not really.
