Keystone Hideout MAX 31SUNROOM
The maker never published an MSRP for this floorplan. Unknown is not cheap. Treat any asking price against comparable models, not against zero.
dry weight 7,530 lb + fresh water (54 gal, full) 450 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.
Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 31SUNROOM's published weights held steady.
