Having towed my fifth wheel a few times over the hogback in Utah (Hwy 12), and across I-70 through Eisenhower I have learned to appreciate how quickly I can climb the pass not nearly as much as how slowly I can come down....
Essentially what I am looking for in a travel trailer is the minimum length that provides two axles, at least one slide, sleeps up to 4, and preferably a rear-living floor plan with large windows in the back.
My wife also is pretty adamant about a shower door as opposed to the plastic curtain.... This may be a unicorn search, but nonetheless it is my quest... ;-)
