^^^ Can you describe what you noticed regarding exterior toughness differences between this and your Kodiak?

I know you know all of this stuff anyway but here are a few thoughts....
It is just my opinion based on nothing particularly scientific and I am probably splitting hairs and of course, there is the question of what is toughness. For me due to past terrain choices, toughness is generally about smucking into and/or deflecting tree branches.
After having rebuilt moulded fiberglas campers and now built out and fiddled with the composite panel CPT shell, I would give a slight nod to the moulded camper for a couple of reasons.
First, the moulded exterior fiberglas on my Kodiak is thicker than the outer layer of the composite panels, no surprise as they are differently engineered and built. Any worst case direct hit with a sharp branch under the same circumstances, I think would probably see the Kodiak's outer skin fare slightly better.
Secondly, are the smooth edges and generally more aerodynamic leading edge of the moulded campers which I think provides an advantage when it comes to deflecting branches (and bugs) . The prow of the Kodiak (and other brands of these type of campers) is angled on a couple of planes where as the CPT (and other Composite campers) tend to have more blunt leading edges along with the relief caused by the use of extrusions to build them all of which makes these campers slightly less able to gracefully shed branches.
Thirdly and I think I am really splitting hairs here but I am guessing that with a blunt force strike to the front or sides of these two types of campers, there would be a better chance of the moulded camper exterior flexing slightly prior to fracturing. With the composite camper's tight bond of the wall "sandwich", the outer skin can't flex into the underlying foam so I think it would potentially fracture more quickly than the moulded camper. My logic with this is that because with moulded campers, any hard insulation is simply glued to the outer skin from the inside with no serious inner layer except for panelling which is also just glued after the fact.
And lastly, the moulded, crowned roof vs. the flat roof may also be a tiny factor in favor of the moulded camper.
For me, it is all moot anyway. Having the wisdom and maturity that is supposed to come with being a senior citizen, I no longer bush crash my campers with the same gusto as days gone by so my new composite panel camper (which I really like by the way) is not going to be subjected to any ballistic destructive testing.......
