Is this Marc of XP? If so I'm sorry if you feel I'm ripping you off.
There are going to be some definite similarities at first glance on the surface but some big differences to, which are important to me. Additionally since this is a home build even if I copied it exactly what would it matter, are we not allowed to self manufacture these days? Creative spirits often reproduce many commercial products. That said I feel I'm producing something unique for myself (if I choose to build it).
Alike:
*Passenger side door
*Rear dinette (but XP is smaller)
*Kitchen on driver side front
*Potentially storage under the bed (just like other manufacturers do, not unique to XP).
None of the above is specifically unique to XP, however its not a bad layout either. When dealing with a certain sized box there are only so many ways to lay it out and there will be some overlapping designs.
That said here's some solid differences:
*I only want 7'-6" length
*I want a twin sized bed dinette
*I don't want a shower/bathroom enclosure to the side of the door
*I don't want a basement under the camper
*My outside access will be completely different
*I'll be using propane appliances, not diesel
*I'd be using a cooler style fridge off to the side of the door, not a build in one in the galley
*I want an opening window into the truck cab, XP appeals to have build in storage all across the front.
ETC.
I'm under the impression the XP is of mold construction, if that is the case it wouldn't seemingly be feasible to produce what I want very easily. Additionally you're producing a very high end product that just isn't in my realm. You've got very high end appliance, core material, etc.
If I build this I'm planning to do a basic polystyrene foam board core with some wood, hand wrapped in epoxy and fiberglass. Much more of a budget minded BOM and I think I can produce what I want out of a camper, fully outfitted for maybe 1/4 to 1/3 the price of your shell (all my labor though).
Again I'm sorry if you feel ripped off or threatened but you should really feel good about the partial inspiration. If I really was trying to rip you off, I'd have already tried contacting you to figure out a few little design details that I'm still working through.
I can tell you've never lost a client in me because your product was always far to high end for my budget/desires.
