I saw your post about wanting to buy a Roadtrek. A few things:
It could be tight with your mom and two big dogs, but you can do it.
Best bet for buying is to subscribe to the Vintage Roadtrek page on Facebook (in facebook, search on "vinatge roadtrek" [without the quotes] as well as "roadtrek."
You can also look on craigslist, but be very careful of scams.
Good luck. And if you have questions contact me offline at mailto:stevebass@gmail.com
