Having done considerable long distance touring / camping when our boys were younger I see 25' as just about ideal - long enough to be comfortable but short enough to park on pretty well any campsite one may select or be assigned, a particular advantage when not reserving ahead of time. Sure, a 34' trailer with all the amenities may offer comfort "just like home" but at the end of a long driving day I'm far more interested in being able to park my camper as quickly and easily as I can on whatever site may be available, particularly on a summer weekend when there's often little choice. Our previous triple bunk bed KZ Spree 240BH-LX measured 26' 9" coupler to bumper, these days is available as the slightly longer
KZ Spree 240BHS in which the two 32" wide rear bunk beds run the full width of the trailer and are especially suited for tall people and offers all the necessities for a comfortable home away from home. Sure, a sofa in addition to a dinette would be nice but not when it means dragging around a longer trailer that would be more restrictive in terms of what sites it may comfortably fit ... given the choice, with our past experience in long distance traveling, I'd take the shorter trailer hands down every time. :B
