I kind of didn't want to reply to this thread.
Just find it hard to see posts that say a certain camper is "the toughest" out there.
Especially with a new design that has only been out there for a few years and only have a handful of campers running around out there.
Doesn't seem like a time tested camper yet.

Yes, Stan you are right, 3 years, 60k miles of testing and only a few running out there is not a time tested camper. However, the construction methods used are very time tested.
The transportation industry in Europe has used this construction method for quite a while (

What I did do was to incorporate well known products, mostly from the marine industry, into a camper shell built like a high end yacht. The XP doesn’t float however, due to some access hatches below the water line. It doesn’t have any seams though, making it virtually leak proof.
It took 7 years to come up with all these new high tech systems to incorporate them into a camper. Sure, it was a challenge to get diesel appliances installed in a removable camper, but working closely with Webasto we were able to figure it out.
The hydraulic system, hardly a new idea of lifting stuff, is time tested. We made the cylinders out of aluminum and added a remote control so you can lift the roof with your thumb. There are also no locks or catches to release. Simply push the button. You also can pump the top up by hand in case of electrical failure.
By bonding all interior parts to the shell it basically gives you a superstructure. Lightweight, no mechanical fasteners to fail and in case of busted water hose no harm done as the water couldn’t do any damage. I also use only marine wiring and waterproof connections, so in case you do get some water in the cabin due to a river crossing, you could still use the camper. There is even a plug in the shell to release the water!
About the Tough Part.
I hit a tree pretty hard a few years ago and only scratched the cabin. Had this happened with my previous pop up camper, I would have had a hole in the side for sure.
Then there is the hammer test. I have had people hit a sample piece with a hammer, and the most we got was a dent.
So yes, the shell and its construction methods are very tough!
Hopefully this gives you an insight of how the XP is built.
