Possibly soon.
I actually took advantage of the 20% HF coupon and picked up my 4x8 trailer the other day. Once I get the paperwork on that done and gather the necessary funds I am pretty much ready to begin.
Sadly, though, I doubt I'll have this done in time to use it this year unless it's for an early fall camping trip.
I have a deck on my house that desperately needs rebuilt. And, since the deck is a story up off the ground, under it is the perfect place to do this build. So, I really would benefit from doing that first.
In looking at this, I really think that the hardest part of the whole thing is the front end. All those angled cuts and such. Really need to figure out how to accomplish all of that.
Might want to simplify that even further. Just do a basic cabinet on the interior. The exterior tongue box can always be added after the fact, if necessary. Just make sure I build the connecting points into the front wall before closing it in.
