Newbie to travel trailers- need advice on selection

You can lift most trailers -- there are various kits available. So ground clearance is not always a make or break issue, if it can be handled with a lift.

If you already know that you like camping, and you live in Denver, you may want to spring for a really good trailer -- the chances are that you will love it and will use it a lot. To put it mildly, Denver is well located for world class camping.
