We are confused and hoping you can help... we have an opportunity to buy my cousin's Keystone Hideout 27' for a really good price. It doesn't have a slide out though. WE have 3 kids and plan on taking a couple of friends with us. Will this be okay or something we regret not having? We have been looking around here and for the same price we could buy one with more features (a slide out mainly) but it would be a few years older. Since we are new to owning a travel trailer, our main goal is to not have too much maintenance and to sleep enough people that we can include our friends and family. Also, another question... I love the look of the smooth trailers (not the corrugated aluminum) like the Trail Lites- are there any advantages/disadvantages to the different materials? We plan on doing mostly fair weather camping. Thank you SO much!
