re: air gauge angles
there's a couple ways to ameliorate this;
1) there are different configurations; one we used to use at the truck tire service business seemed simplistic but worked great then: long stem from handle/ angled two ended air chuck for both airing up as well as taking pressure. 2 different tools with the same kind of head, about a 55/35* angle which fit one dually one way and the other end for the other. Assuming your stems/tubes are mounted that way. Used to be the standard across the country.
2) take it to the tire shop, have them do it & show you the tool you need. Most actual _tire_ shops will be happy to show you & maybe sell you one.
re: galley cabinets.
While our outings have been limited in our own 213, we've satisfied with this:
dishes/cups/misc above sink; metal cook ware in drawer below (WITH sheets of rattle-stopper between; canned good/boxes/in pantry next to refer.
Drawer for cutlery. Our came with an under-cabinet coffee maker that is a toss-up on how neat/easy/handy/in the way it is. Haven't decided yet but no need for coffee pot with it there. Plus it runs on electricity.
Overhead bins along dinette/sofa are various bedding/games. Front overhead storage is games/books/manuals/still getting settled in ourselves.
I built a couple extra pantry shelves clones of OEM. Added wood cutting board that fits the wire stuff on the stove top; controls the rattle & is quite handy. Got a fold-up shelf/cabinet surface extender but haven't mounted it yet.
