Bunkhouse with master bed for tall person (Jayco 28BHBE)

I'm 6'4" with a front queen and entertainment center wall like you describe. My TT came with an RV queen, 74" long bed. I added an 80" long mattress topper which cannot quite fit. I do okay, but I'd like more space for sure. There are several brands that offer residential queen beds, 60x80". Keystone Laredo 291TG for example. Another option is something with a master bed on a slide, like Keystone Outback 301BQ. While the mattress is only 75" long, there is plenty of room for a longer one.
