Tough choice between the RF 100-400 f/8 at the long end, and the heavier RF 100-500, f/7.1 at the long end.
the 100-500 is more a matter of weight than money, but so far I have been impressed with the RF100-400, it is not the EF100-400Lii or the 100-500 but it is nice and light which at this time is more important
Maybe something like this. Looks like the wheels are large enough for rough roads, and can be bought in various configurations.
I was going to buy this to carry my gear at air shows. But I decided not to, since military air bases often have restrictions on what you can bring in.

too bulky, I have a luggage 2 wheeler that I use to lug coins to the bank and my Tamrac Pro12 will sit on it and I can stand my chair on it with a bungie cord... I will try that tomorrow or the next day
