As soon as I saw you were thinking about a VW Bus, I started to cringe. I grew up camping in all sorts of RV's and have owned a number of different ones, as well. But the worst experience ever, was with a rented Wesfalia for a week on the big Island of Hawaii.
I'm sure the models you're looking at will not have electrical issues, smell like vomit, barely run, and will be a little nicer than the one we rented. But still, even if it was perfect, not having a shower was the worst part about it.
Bathrooms are everywhere, that's not the problem. Showers are the problem. You can deal with the lack of storage. You can deal with the cramped quarters. You can deal with the lack of power. But you can't easily find a shower. You'll feel like a vagabond trying to sneak into rec centers where it's posted that showers are only for those using the pool. You'll spend your time on the internet trying to figure out if there are pay showers at campgrounds on your route. You'll be wondering if you can pay to use a shower at 24 Hr Fitness. You'll be Googling for YMCA's and drive to them to find that they have closed down.
Maybe it's not as huge an issue if you're a guy. But that's the only reason I'd never consider an RV without a shower. Unless you plan to camp exclusively at campgrounds with public showers, it will be tough. And that's the point of the Westy, to be able to "camp" anywhere, so I'm not sure I get the allure. But if you're just doing very short trips, or just day trips, it's definitely a consideration.
