This is almost fantastic: after all, while driving, the car looks like an ordinary minivan! Another option - tirdrop trailer from the Australian company Gidget, which also doubles in size if necessary, and all thanks to the retractable liner.

Assessing both options, we noted an increasevehicle weight, the complexity of its design and the occurrence of problems with sealing.
