Since you're only talking about a 3 day trip, I'd be thinking about down the road. I'm assuming you're going to be taking more trips? Or looking for a trailer for other purposes, such as utility? Seems like any old trailer would work for a 3 day-er.

I'm partial to the Nomad because I have one and I love it. The Croozer is a little heavier trailer, probably because of the solid plastic floor. I don't know how well the cover would hold up on the Croozer, but the cover on the Nomad has held up very well for me.
