My thoughts are that I wouldn't buy one due to seismic using the swin-tec slide on their larger slides. A lot use them on smaller bedroom slide but nearly everyone has gotten away from them on larger slides due to past issues. So in my opinion its a chance that I prefer not to take. Everything else probably not much different between makes and models other than floorplan. Something I look at is, can I access frig without running slides out, if not, is frig located on curb side so slide won't be in the street and can I access front bath and bedroom without running slide out if I stop at truck stop and want to rest for a bit. Those are just a couple things I watch for.
