The problem with foamies is they got a reputation for being cheap, budget builds, with no frills, and no design or style. I have seen two foamie campers in person and they were junk. Poorly built, looked awful. My wife seen them before we started our teardrop and said no way are we building a foamie.
That said, and I would never say that at the other site because I would probably get flamed.
There looks to be some nice builds. But there are trade offs. If you are okay with the look of a brick on wheels, then they are great. If light weight is the main concern, then go foam. Are okay with exposed wires instead of them being hidden in the walls, hard to build storage and galley unless you build with wood. And the fact there is little easy to find information on how to build without wading through hundreds of pages of build threads to find some ideas to build.
For me I like the classic teardrop look, I wanted it to have form and function. I don't know if I did it but it should work for us. Just because we are camping doesn't mean it has to look like we are roughing it.
I'll probably look into building with foam after I finish this one. Or aluminum.
I am farther along than this but I don't have any current photos.
