New rv family

[Gilkerfamily]

Hey all.

New to rving and chasing a lifelong dream.

We are About to travel around western part of the country for six months and our 70 for Winnebago brave. Obviously I know parts are hard to come by but I was wondering if there's any good resources you guys have for finding parts should anything happen along the way

Hello, welcome and best to you on your adventure!
As for parts, many can be gotten at NAPA, but... you need the correct part numbers for some since your engine is a heavy duty version.  Use the HD truck for reference. 
Some parts are not readily available.  Particularly brake parts.  So, you'll want to be sure your brakes are up to snuff before leaving as it may cause significant delays if not. 
Also, realize it can be difficult to find shops which will work on these vintage RVs, and know even less about them, so I hope you're mechanically inclined and have tools.
