Don't worry about the length, you will get used to it and some people buy too little and end up wanting another one in a few years. The important thing is the floorplan that meets your needs. Take your time doing your research, read all the manufacturer forums and see what people like/don't like about their MH's, quality, customer service, ect. Go out and look at as many as you can and drive them all, you will develope a sense of what qualities are important to you. Then make your decision.
Although we have had all kinds of RV's/boats ect., we never had a Class A. We originally put our own limit at 34' as that is what I thought was as big as I would be comfortable to handle. After looking and driving we saw that for a few more feet you get alot more options and amenities. We ended up with ours which is actually 36'11", it handles great and it really only took me a couple of trips/backing into spots/freeway driving/city driving to get comfortable with it. When you really think about it you are only talking about 24" to 36" difference in length, which is nothing. It's kinda like the pricepoint, once you find what it is for you a few thousand dollars either way shouldn't make the decision, in reality 34' is big and 36' isn't too much bigger, but what you get inside is usually alot more. I'm really glad we went bigger, as we really enjoy the comfort of the MH and have been able to get it into any CG we have wanted to. Good Luck in your search, that's half the fun.
