Sorry for the slow response.
I took a break from marketing the trailer over the holidays. In January I was approached for a new gig and went through the interview process. February I started the job and have been traveling a lot.
sjk99's post is correct. I have it on craigslist.
An update from a prior post. I tried to get the tank cap made by a local machinist with no luck.
Feel free to ping me with questions.
