I’d like to see the 3 season door available for these models. The wife and I are getting ready to buy a toy hauler and have decided on the Heartland brand. We almost pulled the trigger on a 373 this weekend, but found out the 3 season door isn’t an option. Says it is on the website, so I emailed someone at Heartland who confirmed it is not an option. Is this something that may be considered in the future as an option ?
