TheLuvShack makes some good points. Because PCs are built 21 to 31 feet, they offer a flavor of plus's and minus's pending your travel style, duration, agility requirements, and who comes along such as kids and/or pets.
For example, my wife and I travel together, just the two of us for 3 to 4 weeks at a time. We love national parks & monuments, and other public lands, so agility and boon-docking are higher priorities for us. We also take full advantage of Walmart's hospitality along with rest areas. We do our best to avoid RV parks. At our destinations, we are always out and about in our tow vehicle with exception to terribly rainy days. Our 2350 fits our travel style perfectly.
Other people have other travel styles determining the type of PC that meets their needs best.
