RV shows are a great experience for anyone who has never gone. It's a great chance to see a lot of RVs in a relatively low pressure setting.
I just bought my 5th trailer over the last 15 years or so (bought/sold some due to the economy and having kids) and totally agree that research is key to making the right choice. I spent an absolutely ridiculous amount of time on manufacture's websites looking at floor plans and on the net shopping prices. But, in the end, I ended up with a perfect trailer for my family and feel like I stole it :)
