Walking it in and out in this would also not freak out the elderly democrat former hippie that lives in 3C. Though guitar cases also worked well for transport. (but only if you have a concealed carry permit!)
Make sure you have a strong clothes rod. Not those thin white shelf things made of wire and hope.
You you actually make a home project out of this. Go to Salvation Army and get the right size garment bag. Sew in some Velcro and start adding gear.
Plus the right garment bag will already have lots of pockets and compartments.
--Just don't run it through the scanner at the airport. You might wake the TSA guy.
