Ok.. so brand is settled. But, you did ask if 'they' were too big.. but without a model or a size, kinda hard for anyone to suggest they are 'too big' or not. There are plenty of different models in Eagle and Northpoint to choose from. Some larger than others.
Alot of people full time in pretty large rigs, so depending on where you want to stay, you will either be fine, or have a tough time finding spots.
My assumption of course is that you are asking about size in relationship to size of spots in campground.
