Hi rfanti -
I'm pretty new too on this forum but I have been doing this for a few years (RV ing) and I'm on my second coach.
Like you, I bought my first one used just to see if I would like it.
I take it from your post that you are looking for a coach and not a trailer/fiver. That said, your timing is good as a buyer since the recession has cratered pricing a bunch and $30k should buy you a decent "starter" used coach.
I notice you are in Tenessee and not so close to Texas, but just the same you may want to check out Used RVs, Motorhomes, and Consigned sales - PPL Motor Homes
PPL is one of the largest, if not THE largest, dealer in consignment RV's and they are located over in Houston. I've never bought a coach there but I know a few that have and they all report a good experience. As a web site, it's a good place to go just to get a feel for what's out there in used coaches (or trailers) and that can help a lot when you then turn to your local dealers and private resellers.
Also, you may want to expand your post to give a better description of the size/model of the Foretravel you looked at so that other's can figure out what you consider small. Naturally, with a family of six, you need room to sleep six and most coaches will do that, although not necessarily in total comfort for everybody, depending on their ages.
By the way, Foretravel is built right here in Texas (Nagadoches - oldest town in Texas) and has an excellent reputation. I can't speak to the model you looked at, but many RV'ers consider a used Foretravel to be a pretty good investment. Foretravel was one of the last to offer slides on their coaches (they say they wanted to wait and "do it right" and if you see one of their new units, you would probably agree that they accomplished that goal) so I'm guessing the one you saw had no slides, based on it's age. I'm sure that once you see a few DP's or Gasers with a slide or two you will lose that feeling of "too small".
Some of the newer coaches feature bunk beds which are a real good option for larger families like yours. They sleep a couple of kids in a relatively small space and don't need to be "made up" for each night out. However, I'm not sure you will find this feature in too many used units in that $30k price range. But others on this forum may have better ideas.
There are dozens of threads on this forum dealing with what to look for and consider in a used RV, so dig in and start your studies and I'm sure you will learn a LOT that will apply to your search.
Don't get in a hurry and buy the first "good deal" you find, since every used coach is different and their are MANY to choose from, especially in this market.
