Talking about aerodynamic design, I did learn aerodynamics in my younger years and when aerodynamics don't have mathematic formulas and require wind tunnels for design, main rule is that shape of the front has neglectable impact on air drag, when >90 % depends on smooth rear.
I see this camper has square rear like most, while narrower front lower the comfort.
In my travels I had 2 campers. 12' Lance and 12' Fleetwood.
When both campers had similar floor plans and similar weight, Fleetwood being basement camper was about foot higher.
Regardless expectation that higher camper will lower mpg, that did not show clearly on my records and I enter each fill up on fuelly.
With camper I always set CC to 60 mph, so that is consistent.
Actually checking my records the taller camper shows better mpg, but I think that is due the fact that I had new truck, who with lower camper was in break-in period, while having over 20k miles on odometer with higher camper, the engine start showing better performance.
Either way, the differences are within common differences due winds and different fuels.
then you also know disrupter angles can be used to mess up the airflow as it leaves the back reducing the amount of drag created by the low pressur zone behind the unit. this is the premis air tabs work on and several others. untill I could see one in preson to be sure, but it looks like the shap of the sides might act that way. will it be totaly effective I doubt it. heck the tail fins they put on semi trucks dont work that great as you would have to have such a long cone it would be stupid. air flow disruption is the way more practical way to go. I am still digging into it on there site to see if I can find more info on this. I do like that its a direct canper to fram mount, no tie downs though..
as for the porty potty, I'm with you there. thats why I wonder if there is a possibility of different floor plans or maybe a longer unit in the future. they say on the site they kept the longest at 8 feet so your tailgate can stay on and back up cameras and such would still be availble. how hard would it be to get a factory camera and mount it to the back of the camper and plug in when you take your tailgate off. thats what I am thinking of doing with my old one.
