We have both an Aliner hardside folding camper and a FWC popup camper. Our Aliner hardside panels do not have a tight seal in the vertical position and so are drafty while our FWC is airtight. Aliner's are very light, lighter than our FWC. Aliner did produce a popup hardside truck camper years ago but sales were very poor. The Aliner has more floor space than our FWC but less head room. We strongly prefer the geometry of the FWC, space at eye level is much better than space at foot level. Our Aliner is water tight since we were in a 60 mph wind driven rain thunderstorm without any leaks. An NCO truck camper would be a better living space than an Aliner because of eye level space and there are many different makes and models of NCO which can be very light.
