Its not a "real" truck, but neither are most SUVs these days - most are unibody and are reasonably tough, and actually safer than BOF trucks of old (and current).
Since its like a minivan chassis or something like that, it has enough load carrying capacity for some basic tasking, like most homeowners and light duty users.
There are all sorts of varieties of light, medium and heavy duty trucks.
This happens with true, real trucks (say, 3/4 ton commercial pickups through class 8 or whatever is biggest), and nobody blinks an eye - the right truck for the job and use profile. Why should it be any different with these types of trucks?
Don't think Id ever buy one... But they have their place. Vehicles like this have been built since at least the early 60s.
