Again thanks for all the replies guys. Glad I asked this question didn't think of all this other stuff. Yes I'll have my wife, three kids, my 90lbs chocolate lab, fire wood, fishing tackle, and cooking stuff I'll be towing along also.
The place I bought our camper from is doing an inspection on camper to make sure everything works. Then when I go to get it they will go over everything with me to show me how to work the camper. The sales manager worked with my father for over 20 years selling cars here in the Omaha Nebraska area. However I still will be going over it to make sure everything is working. We did have a hand me down camper from my father but didn't fit our family at all. This new camper is my first purchase of a camper so I'm really thankful for all the suggestions here guys I really appreciate it.
