To address a few of the latest replies....
1. I wasn't necessarily talking about bringing nieces and nephews on this 1st trip, just in general. Depending on when we get to do it, I wouldn't be worried about having them though. They're 10-12 so not babies i need to cater to. they'd be right there helping with whatever we're doing to set up.
2. I definitely wouldn't want it delivered. Towing the trailer, backing it up, getting weights, and seeing how well it all tows on the road is absolutely necessary to the learning process.
3. The cost of the trailer and site rental does add up. I don't see myself renting both for a long time but either way, doing it once or twice a year isn't too bad. 4 days seems to be the sweet spot going this route and there's some good rv parks less than 4 hours away in all directions.
