There are a couple of Blogs by people who also have a Roadtrek 190 and have posted fairly detailed "how to" info on a wide range of topics. This was quite helpful when I was considering what to purchase, and as I learned how to use its various systems. There was also a lot of good info on upgrades & modifications that might be useful.
I also find the detailed info on various destinations I'm considering to be extremely useful. Usually, it's more comprehensive than what you get from RV Park Reviews or similar sites.
So keep blogging, folks; you're saving me a lot of time and improving my RV experience.
