Jayco is probably the biggest so look over their models, go to their website, look under travel trailers. Gets a bit convoluted at that point as they have hybrids in several model lines. For a start go to the Jay Feather Ultralight and look at the X17Z. What you see is a hybrid with 2 bunks. Look for models with those to be in a hybrid. Find a local dealer or 2, call them and see what models of hybrids, if any, they have on hand and go take a ride. Ignore the model # as an indicator of the length of the unit, check the specs instead. Also check out the Rockwood Roos, they have 80" beds and some very large/nice layouts in the sub 25' length. I don't know if anyone makes a hybrid over 25'!
With a 1 ton you can pull any of them, most roomy are the ones with a slide of some sort, makes a big difference. There being 3 of you you can go with a 2 bunk, DO find an 8' wide model and check the bed sizes, many of the smaller trailers have what they call RV queen beds, they are usually 75 or 76" beds and won't work for tall folks. Make sure you look for the 80", also check the interior height, keep in mind the air conditioners hang down a couple inches. Other then that I just made sure that when sitting on the throne I could close the door.
Something like the X23B may work, lots of room, under 25', the beds are a tad small at 78". The U dinettes make a big difference too in seating comfort on rainy days. The couches are for the most part fairly cheap. As far as your price range, I have no idea, been a long time since I looked.
You can also check out RVdirect.com, probably the best prices around if you don't mind driving to Albany or Buffalo to get your trailer. They carry Rockwood Roo's (Forest River Product) as well as the Jayco's, both good brands. Once you pick out a model you can get a quote from them and use it to dicker locally if you prefer. Many have used rvdirect with good results.
If you're not aware, unless you have a diesel, gas mileage is down around 10mpg with any of them.
Good Luck
Happy Motoring
