I don't know if there are any after market options for a netting on the overhead bunk, but I am sure you could fix up something. As far as the levelers, some people add the HWH levelers as an aftermarket option and I think it costs about $4,000. It also adds to the weight and if you plan to tow a car, it may affect that. We have 2013 Via which is on the MB chassis and we love it, great mileage, and it can go just about anywhere and is easy to park. There is another forum specifically for Winnebago Views on Yahoo,
View and it will provide you with lots of information about everything on the View. Also lots of opinions on to install levelers or not. We did not install them on our Via, and it is not an issue for us, so you may want to drive it for a while and see if you think you need them. I do carry the little yellow leveling squares and occasionally have to use them on uneven campsites. You can look at RV Trader to get sales prices in Colorado and nationwide,
RV Trader. You will have to register for the Yahoo View Group, but the information is worth it.
