As a full-time RV'er (off & on) since 2010, plenty of experience here. I'll just get into generalities right now, but if you have specific questions I'm happy to address those as they arise.
I'll start with the obvious: an Airstream OMG I'm so jelly <3 Like, seriously, that's sweet and yours looks to be in excellent condition. I've been toying with trading the magic bus towards an Airstream, but for now I'll just have to live vicariously through you The interior of yours is gorgeous, so it looks like you have a great starting point, whereas my magic bus looked like Carmela Soprano tripped acid in the late 80s and decorated it accordingly (seafoam green and dusty rosey floral grossness and everything was matchy matchy and just ugh) and all of it eventually had to go. Mine had CARPET, if you can imagine, which was just disgusting since this RV was used for fossil hunting and fishing expeditions which means lots of delightful sand and dirt was buried underneath the padding when we ripped said carpet out. Carpet is a hard pass in an RV, at least for me. Beyond that, I'll leave decorating up to you because my decor tastes can be a bit weird and yours are impeccable from what I've seen
Rule #1: multifunction. Everything needs to be able to handle as many duties as possible. Storage and space are precious in an RV, and weight matters when traveling. Lighter is more fuel efficient; so the more function you can pack inside it in fewer items, the more comfortable your time in the RV will be. I'm not seeing any "basement" storage in the pics, so your space will be even more precious. Those basement storage compartments make handy places to store outdoorsy items like chairs and athletic gear and such. Even pillows have weight to them and take up space, so consider things like decorative pillow covers or poufs that you stuff with blankets or towels, rather than pillows and poufs that don't store these necessary items. Really THINK about ways to trim weight and increase efficiency, even more so than RV designers already do (running furnace ducts through the water pipe chases is super smart). Multifunction items are your bestest friends in an RV. RV dwellers need one good cast iron skillet (can be used on a campfire as well as a stove), one good pot, a good chef's knife, and a fork; no whisks and flippers and rice cookers and panini makers and potato peelers and and and and... There are untold treasure troves of experience in countless forums across the 'net, and I dove into them AFTER we moved into our RV when I should have done so long before I did. Also check into subreddits like van dwellers and other unexpected places because van dwellers are MASTERS at efficiency and minimalism. Tiny house forums, too, can be invaluable.
Almost as important as rule #1 is rule #2: climate control. An RV is basically a giant car, with the "greenhouse effect" to go with it. Summer heat turns RVs into ovens, and winter cold turns them into meat lockers. I'm only seeing one roof unit in pictures, so anything you can do to insulate and block sunlight will be massive. I wish I could afford to gut my magic bus and have spray foam installed in the walls; I also wish I could afford to get dark mirror tint on my windows. Even if I had those things, I would still have to consider environmental factors when choosing a place to park. Shade is huge, and hard to come by in some places; here in north central texas I try and make sure my front end (the most concentrated amount of glass) faces the MORNING sun rather than the evening sun. That works well with the 2nd factor that helps: prevailing winds. Our prevailing winds are southerly, so being able to have those prevailing winds hit me broadside (rather than head-on) at my current park positions my screened windows to actually work beautifully with my desire to have my windshield facing east. You don't have a windshield and driver's door, so you'll have to figure out your RV's optimal positioning, but it won't take long. Reposition it in your own yard if you need to experiment; that would have been invaluable for Sunshine and I. If the lights in your Airstream aren't LED, get them changed out ASAP. The standard automotive bulbs generate heat, which matters in warmer weather. In colder weather, our dual propane furnaces were super nice, but they ripped through tanks of propane in an astoundingly short time frame (and texas winters are actually pretty mild). I use an electric blanket and a ceramic electric heater to supplement one of the propane furnaces; that furnace is necessary to keep water lines from freezing since they all run through the same pipe chases. I also have a water hose with a heating element wrapped around it so that my water supply doesn't freeze.
3. Leaks. Someone needs to go over the exterior of that RV with a microscope. Every window, every vent, every light, every anything that passes thru from exterior to interior, and any seams in exterior as well. This magic bus was nothing but one gigantic water leak when we got it. Windows leaked, plumbing leaked, roof vents leaked, we even had water getting in around the little yellow lights on top and I've had leaks at seams in body panels. We got surprised during a rain event when water started pouring in through the little handle inside that cranks the tv antenna up on the outside. Check everything, then check it again. I recently had to climb up on my roof to recaulk a few places after yet another texas rain event, and that was only a couple of months after we recoated the entire roof with an impermeable membrane. It had not necessarily been done with care, so the seams and a skylight had some cracking that let water through.
RV refrigerators. The ones that can run on propane do not defrost themselves. For shorter trips, not a problem. When we first moved in the magic bus, I had to defrost the fridge & freezer every 4 to 6 weeks. What a pain that was, since the fridge was always full since we LIVE here. When the RV fridge died, we found a standard fridge that EXACTLY fit the hole. Upside to that? It holds more stuff than the old RV fridge.
In an RV, the water heaters are generally tiny and insufficient. Get used to very short showers LOL
Laundry. Even just little old me, who will use a towel more than once before washing, generates a frightening amount of laundry. Even little old me, living alone, has a conundrum over what to do with dirty laundry until I have time for a laundromat. Same for dishes; some days, I would almost rather use disposable stuff, but for environmental reasons I bite the bullet and deal with dirty dishes fast. My corelle dishes are nice and thin and lightweight yet fairly indestructible, so they work with rule #1 about weight/efficiency and they fit in my tiny dishwasher (my dishwasher is a freaking LUXURY). I did away with the stove and range combo, put in a 2 burner cooktop and convection microwave so i could have a dishwasher where the oven used to live.
Thise are the big things that spring to mind right now. If specific questions come up, please PM me or just email me at cynthiawalkerwhite at gmail and i will be happy to try and answer.
Final note: never ever let yourself run out of holding tank treatment. Your nose will hate you if you do. Look for formaldehyde-free, as those are way friendlier to septic systems and sewers. I even dump ridex in mine from time to time, to eliminate any buildup in my waste holding tanks.
