what people ???
the most profitable to most international movers are lift van. the reason is: they consolidate other lift van in 40' container and from that the profit a lot....but basically you will need to go with your need and do not calculate how much profit.....
all
international movers that advertise on this site will provide with both prices: lift van or 20' container.
you will need to go with the best solution of your needs
