Hi Pete, great site and well done for getting the whole family involved in such a worthwhile adventure.
I would just like to say that you might want to consider carrying a portable hand winch such as a tirfor. The reason i mention it is that it is quite easy to get bogged down when towing a trailer, and you may have to unhitch the trailer to get unstuck. If this happens, it may not be possible to recover the trailer with a tow rope. The tirfor can be used to pull the vehicle or trailer in any direction you require. I understand your reluctance to take a high lift jack, but this could also double as a short pull winch with the right combination of shackle and shortening chain etc. Just a thought, Regards,
