Purchased camper new. We like the size and layout, for two adults. Easy towing with our short bed half-ton crew cab with tow package, weight distro hitch, and anti-sway bar. Front contour of the camper seems to add to easy of towing, and it pulls well on smooth and lightly uneven roads.
Craftsmanship seems less careful than our previous brand, but after 6 years the seams and joints are still intact. Shower leaked between stall frame and stall pan from day one. Twice replaced toilet flush valve due to cracking and shear, now disconnecting behind toilet during frigid winter storage. Have read this is an issue for the toilet brand (and owner's winterizing), not Keystone.
Keystone service seems good. Furnace quit just past warranty, but they covered. They have also covered recalls without grief. Emailed questions to Keystone have always been answered in timely manner to our satisfaction.
This unit's size may be small for more than two persons, unless you like close quarters. Not much kitchen counter space. We added a hinged extension. One electrical outlet for kitchen under overhead cabinet, too high for our appliance cords. In this floor plan, no outlet at all in slide, so run cords if you want to plug in while seated at dinette or sofa. All cushions remain comfortable after six years. We upgraded mattress immediately after purchasing unit. Jackknife sofa bed okay for 5ft person. Bathroom is very tight quarters for us but not a deal-breaker. Our shower door swings out, you may want a radial rolling door design instead. Less water on floor when exiting shower.
Roof is crowned for water run-off. Our model year has flat interior ceiling with low but adequate head clearance for 6ft tall person, but newer GT models are crowned for greater head clearance. Our model year also does not have walkable roof-- thinner ply under layer creaks when I crawl on it-- so ours is a challenge to self-maintain in the middle of the roof. Use an additional piece of thin ply to crawl on it. Newer models may have walkable roofs. Our roof membrane has performed well in extreme cold, snow, occasional small hail and summer direct sun (regular maintenance is key). Underbelly is enclosed but not insulated.
Decorative seal on outside of one window shrank over time but window construction did not seem to allow water to seep in before we caught and repaired the problem. Scissor jacks came installed at 90 degree angle on frame, but could be reinstalled at 45 degrees for seemingly sturdier stabilization.
All warranties have expired on our unit so this is an all-around fun unit to tinker with, modify, etc. Utilities are easy to locate and trace. Would we buy again? No need to, as long as we use a half ton truck. But yes, would buy a GT Passport again. Definitely go with a walkable roof if buying a Passport GT new, and install one of those name-brand whole-camper fans into both roof vents.
