I've been away for a while, but wanted to say thanks and post an update.
I went ahead and ordered a trailer last week. After visits to several lots and looking at a ton of trailers I pulled the trailer. Ordered a 7X16 V-nose with a ramp door. I had them raise the roofnto 6'9", install 2 windows, upgrade to LED lights and add back up lights, install the interior with screws, and build it with 16" OC floor studs.
It should be ready May 23rd, but here is the catch. My dad couldn't resist a good deal so he bought one too. I am picking that one up on the 23rd to deliver to him and then going back for mine. I should get a commission or something

First order of business will be to insulate the walls. Then outfit it as necessary.
Thanks again, it looks like I will be here to stay
