Once these E pickups hit the market, it wont take long for the buyers to realize the limits of the vehicle, within months you will start seeing them with their respective tt's in tow, and you will be hearing a buzz in the background from all the generators in their beds running for hours so the truck can get back to town for more beer and wine along with a bag of ice.
The plus side of this is that it may restrict most of the owners to staying in commercial campgrounds where they can get a 50 amp plug for their truck, and no doubt you will see sites where a truck is on the 50, and a trailer is trying to run from the 30 at the same time.
