I think we're pretty minimalist in our Roadtrek E-Trek. I hate clutter so we have to make it all fit in the storage we have.
Do you have a propane stove or induction burner? We have induction, so that is the fastest way to boil water for us. We actually have one of those instant hot water dispensers as part of the van's specs, but it uses more energy (and is slower). Second choice is the microwave with a glass measuring cup, which has multi-purpose uses in the van.
I bought a set of nesting induction cookware with detachable handles to save space, and I'll admit they were a waste of money. I use them as mixing/serving bowls more than I cook in them. Since I have a major electric system, I prefer to use a vintage electric Dutch oven for cooking. I also sometimes take an Instant Pot, but it's harder to find space for on longer trips when we need more stuff. For the induction burner I prefer a vintage (lead free) enameled tin saucepan with a spout. It takes under a minute to boil enough water for one travel mug of tea.
I raided our home stash for various linens, but we also had some microfiber towels from previous camping, which fold up small and dry quickly. I don't like how they feel though, so I have regular towels.
Instead of a drying rack, it was recommended we use a silicone drying mat since it takes up less space and can cover the induction burner, meaning we don't scratch the burner when we rest things on it. It doesn't take away any counter space. We always hand dry the dishes anyway, since space is at a premium and I like things neat. But you always throw down an extra kitchen towel.
Skip the fancy RV sewer tank packets -- your black tank is likely much smaller than most RVs. We use Happy Campers RV tank treatment because it's a natural powder we can measure out proportionally for our tank. I've been using the same small container for nearly 5 years.
I might want a hand vac if we full-timed, but we don't do I use a cheap hand broom and dust pan. I think there's a folding regular broom in the back storage, but I don't use it in the van. Sometimes the guys use it to sweep the RV mat/rug.
Speaking of which, depending on where we are going, the RV mat is essential because it keeps so much dirt outside and gives the dogs a place to lie down that isn't dirt or mud. We've had the same one for almost 20 years.
Hmm, I keep a sunhat in the van at all times, and sunscreen too. I actually keep a toiletries kit in there even though we don't FT -- you never know when you might want some dental floss or Tylenol.
We splurged on Helinox chairs for the van, and they are worth it! We only carry large camping chairs on day trips, when space doesn't matter as much. Even then, the guys mostly prefer the small chairs.
IIRC, your LTV is a B+, so you probably have a lot more storage than we do. For clothing on longer trips, we use packing cubes since we already had them, but for the weekend I put my things into a small duffel that fits in an overhead bin.
This is a tip that some RVers won't like, but with a small black tank, I prefer to keep any toilet tissue used only for urine out of the tank. I have a zipper storage bag I put the tissue into, and keep it along side the commode. It really doesn't make much different to dispose of it this way, and I'm going to wash my hands anyway. Doing so has more than doubled the length of time we can go without dumping the black tank (oh how I wish a cassette toilet had been standard!).
Have fun!
