About travel trailer
 

I have one trailer in my garage. Nobody is using it now. I just made a research to convert this to a travel trailer. I found some well built container homes here www.securecontainer.ca/containers/container-modifications . I would like to know about the possible modifications that can apply to 20 ft shipping container. Can somebody help me with your suggestions? If possible share the approximate cost too.

I don't have any experience doing what you want to do, but I am sure that there will be plenty of advice for you. The only thing I have gathered from a project like that is to figure out what it will cost you then double it!
