We've been travelling on our own for 7 years - in more than 20 countries including to Alaska, Mexico, Morocco, Iceland, and Central Australia - all destinations that many RVers refuse to even consider doing by themselves and we have never had any problems regarding safety, health care, language and fitting in with local cultures. That doesn't mean we never hook up with another traveller for a day or two or three but that is always on the basis that it continues until one of us decides not to continue and no reasons need be given.
Only twice have I travelled with others - one was 40 years ago and ended amicably after a few days. The other more recent one was with 4 vehicles and one of the group turned out to be so incompatible with the three others that it just wasn't possible to continue.
We have come across some pretty large convoys and there is always quite a few who will admit that it hasn't worked out as well as they thought. One reason is they hate having to work to a strict timetable, and they really really hate having to keep up with the high average speeds that the timetables sometimes demand.
{we came across one caravan in Mexico where they travelled several thousand miles to get there and the first thing they did once they got settled was endure a long amplified chat from the waggon master followed by an exciting session of bingo - also delivered through a distorted PA system.}
