I won't vote, because I haven't built yet.
HOWEVER.... The one thing I would change is just going for it once I found the Generic Benroy plans, instead of watching everyone else build for the last 2-3 years learning what THEY would change.
I started out looking for plans for a small travel trailer - I didn't even know what a teardrop was until I started looking. My intent was to find plans and build right away using as much recycled material as possible. Well obviously that didn't happen - instead I got caught up thinking about what I want - and still have nothing built. Had I just gone for it - I'd have a few years of ideas down for the unavoidable teardrop #2.
What I can say though over the past two years I have gone from wanting a Grasshopper design to a Benroy to a Grasshopper to a Benroy to a Grasshopper to a Benroy to a Grasshopper.... but I do KNOW for certain after seeing CaseyDog's CaseyKraft 2
I really do only want very minimal cabinetry - that just seems far too functional to not be good.
