2026 Keystone RV Springdale Max

The 31SUNROOM is named for the feature that defines it: a rear sunroom addition with double-stacked windows that turns the back of the trailer into a proper four-season bonus space. When it's raining, that's where you sit and watch it come down without being stuck inside. When it's nice, the windows open and you've got a screened room that bugs can't get into. It's a different way to use a trailer, and once you camp in one, it's hard to go back.

The front bedroom is fully private, sleeping four total between the bedroom and main living area. One slide in the kitchen zone opens up the living space. At 35 feet 11 inches and 7,550 pounds dry, it's in the same weight class as the 3100XBR but with a very different camping style — quieter, more oriented around relaxing at the site than maximizing sleeping capacity.

Max-line construction throughout: the sunroom is built to Keystone's premium spec, not an afterthought. Standard Max features apply — tankless water heater, 30,000 BTU furnace, power awning, AlphaPly TPO roof, and the upgraded finish details that separate this tier from the Classic line. The 31SUNROOM is for the camper who's done running from the weather and wants a trailer that works with it.
