I'm thinking of upgrading my 2000 Foretravel non-slide to a 2002 to 2004 Foretravel with slides. This is about the years that fit my budget. I'm trying to find out what issues to look for in the newer models. I believe most of the running gear is the same as my 2000, but if not please let me know. <br/><br/>Cap issues are one issue I know about, but how do I know if it was...
