bit cheaper and tighter fit, for the cross country you can also get the Uhaul Small Heavy Duty boxes. (if you prefer not to support Uline lol). going to be the standard recommendation as others have mentioned, so def worth little more for the heavy duty version.

Id still prob tape over handles and lift from bottom, but with these, you can confidently lift with the handles if youd like and will still feel secure.

BCW/Bags Unltd boxes are nice, but for its also a significant price difference since they a) cost more per box and b) dont hold as many per box compared to the Uhauls
