1) It is only 80w.
2) You have to spend time setting it up and putting it away.
3) To make up for the smaller size you need to keep re-arranging it to track the sun.
4) More chance of it being tripped over or walked on if left out at night.
5) Chance of being stolen or lost. So it won't be generating power when you are parked away from your campground during the day because you won't be able to deploy it.
6) You want to keep the cables as short and thick as possible to reduce resistive loss. Portable panels are more likely to have longer thinner cables for convenience.

I would add one more, for those that use their truck campers, out west.
The Wind.
On many occasions, I have watched people scramble, out of their RVs, to catch their expensive and glass faced Solar Panels blowing in the wind. Many of them tie them down with shock cords and this only adds to the excitement, as they take the shape of towels, blowing in the wind, as they become airborne.
Portable Solar Panels are a good idea when you are less likely to go out and do things, during the sunny time of day. Many of the retired people, that go to RV Parks use them, as well as those that want to grab some Sun, for short stops. So, they are useful, but my experience with Truck Camper people, is they are more active of a bunch, to sit and watch the Sun move from one horizon, to another.
