What is the max length travel trailer you think is practical

We like two recliners, free standing table and chairs, a big shower and bathroom, and a full size residential 80" queen bed. 28' seems to fill those desires. At 32.5' overall, we haven't had any trouble with fitting into sites at campgrounds or squeezing through gas stations. Towing hasn't been a problem with the F250 with or without sway control.
