The best one is the one you buy!
We have been camping for 35+ years, been through a few trailers and spent the last 3 years shopping for new one.
As someone mentioned, look at Northwood Manufacturing. Their sister company is Outdoor RV in Oregon, with the Glacier Peak being their 5'r line. That's what we ended up with after shopping till I wore out our shoes. They are not perfect, but they aren't a hunert-thousand bucks either. Look far beyond the glitz and check construction quality. As an example, they run 16" tires, frames specifically made (not by Lippert) for each model, bracing on the frame by spring shackels, shock absorbers, drilled and screwed joints, bigger appliances, higher-end appliances etc. It goes on and on.
Having said that though, they didn't have a floorplan that we really loved, but the quality we wanted wasn't found in anything else in the price range.
Have a look....might be for you, might not.
