Understand not wanting a slide. I really didn't want one either. But you wish list is hard with out one. Jayco has a floorplan with bunks, but not quads. Apex has one with quads but with a smal slide. 5290 dry,
My Apex has 2 full beds for bunks, sleep 4 easily back there, 10 all together. but it too has a small slide, and by small, I mean it does not slide out but 18 inches. You can use the TT with the slide in, and still use the TT as you would with the slide, out. 4811lbs dry. Your Expe will tow it easily. IF it has the 5.4. I know that because we towed our heavier trailer with a 2002 Expe, with a shorter WB than you have with the EL. It towed our 6000lb TT great.
