The Brave is a great coach. Winnie didn't really stop making them, they just changed the name (to Voyage). The Brave was a step below the Adventurer; not as "polished" but with the same solid performance (chassis & rv systems).
Understand that not having a slide-out can affect your resale of the coach when you go to 'move-up' a few years from now.
If the '99 Brave has OEM tires, you will need a new set; figure $1,600 on that. Also make sure that the coach has been used several times within the past year; -coaches that look great and have low mileage but no 'use' can be problematic (brakes, exhaust, furnace, fridge, are some of the things that need to be closely inspected).
Go to the "Find" tab with magnifying glass above; do an advanced search for "Brave" in the Winnebago Forum over the past 3 or 4 years. You'll find lotsa good info to help you make educated decisions.
Best of luck, and keep in touch with us.
