Is it realistic to start in April and have my mobile tent ready for Mid July vacation?
Dave:
It all depends. I built my tear and it was campable in six weeks. I work full time, although I did take a couple days off during that time for the build. I built a fairly simple design, without a lot of the creature comforts, and detail that others have.
If you are retired, I would say it would be no problem at all, if you work full time it's gonna be tight. I also was forced to work outdoors, so I lost a couple weekends to bad weather, and pretty much never worked past dark.
