Me and the family are very new at the camping thing. We are a family of 5 with a 12, 10, and 5 year old (ALL BOYS), and want to make camping a part of their memories. We just purchased a 1999 Coleman Niagara at a steal($800) that had been sitting for years and the original owners only used a handful of times. It has all the bells and whistles, which we are so happy with, the inside still looks brand new and the outside needed a good washing. Seeing that it had been sitting, there was a mouse problem, so right now, it is at the RV shop and waiting to get a new Canvas (hence, paying a dirt cheap price to the original owner). We are a little concerned that the top of the camper dips a little, but there are no cracks or anything that we noticed. So hope that is ok. We are in Wisconsin, so I am sure that our first official camping trip with the new pop-up will not be until next year. Seeing that it is in the shop, can anyone tell me if it is beneficial to have them run through everything and make sure everything works (air-conditioner, stove, furnace, water valves, shower, etc) or is that something fairly simple that we can figure out ourselves and save the $? Also, I think one of rodents had a field day with one of the mattresses, so I am wondering where is the best online site to get a replacement mattress or cover? I am really happy with the camper, just hope that we are not investing more into it than what we should. And thinking ahead, where can I get a list of what to keep stocked in the camper? I want to make sure I am prepared as most I can, particularly due to the kids. I am so excited! I will post pictures eventually when we get it out of the shop. Any advice for us as new campers is greatly appreciated!
