Absolutely, mine was a case, as it turned out, of a gradual build up of grass & seeds from many previous remote, often solo, travels, between the Auto Trans Cooler and the radiator which was not clearly seen but as soon as I took off the bash plates in the morning it was evident what caused the issue in this case - took about 2 hours to clear it all out, glad I took the easy way out and headed south in the dark, solo, finding a clearing some 5 hours later, and was able to clear the issue - I also had VKS737 monitoring my situation so my personal safety was never at risk.
My personal opinion is that so long as you take all the precautions, brutally honest with yourself and not put other peoples travels at risk and feel confident that your vehicle can withstand the rigours of remote travel, then there isn't much more you can do.
