Needing the bunkhouse really limits your choices and with a 1/2 ton tow vehicle you have a finite limit on how much you can pull.
Drop the bunkhouse requirement or buy a new truck and your options open right on up.
I know what you mean about non-slide models but they are very very few and far between.
It's not a bunk house, but Arctic Fox makes a super popular non-slide TT that you can pull with your truck. And, they have a great reputation for being a great built TT. I know, I had 3 of them over a 12 year period before we switched into motorhomes.
You might look at Winnebago "Minnie" models too. They have two bunk house models one 25' and one 28'. Winnebago wanted to get back into TTs and purchased the Sunnybrook TT company during the last recession. So, the old Sunnybrook factory is now making Winnebago's travel trailers. Sunnybrook had reputation of of being a well built TT and WBGO has worked to keep that quality in their towables.
Winnebago also purchased Grand Design RV and has let them run independently since the purchase. The Imagine 2400BH is a smaller bunkhouse model that is just at the limit for your tow vehicle.
