I bought a 14' Cargo Mate Blazer trailer off of craigslist and rented a uHaul trailer to get it to my driveway in Santa Fe.
Inner dimensions: 12' 7" long, 5' 8" wide, 6' 2" tall.
I'm going to be out of town for something like the next 2 months, so very little actual work is going to get done on it till mid July. I'll be mostly developing the design, sourcing materials, etc until then.
