I had a center stand on the bike. It is a given the it would only on a sturdy surface, or some way to may it sturdy. Most dirt back roads and Forest Service service roads generally were firm enough.
The front wheel is a bit tricky - a friend is helpful here - as you have to carefully lower the forks to the ground. The rear came of quite easily. There are also a number of jack braces out just for holding the bike to remove and install either wheel.
However, pre-sliming the tubes is a much better solution. It really takes a large hole for the sealant not to work. Sidewalls, of course, are another matter. You blow a sidewall, tube or not and most sealants will tell they don't work for sidewall blowouts.
Only once did I have to go throw the replace the tube routine. It was a bitch! Breaking the bead took forever. I believe the ordeal lasted a good 2 - 2 1/2 hours. By then my friend and I were exhausted and sweaty.
The OP mentioned back roads and forest roads. Carry a tube, tire irons, and a small 12v air compressor (with an SAE plug) just in case, pre-slime the tubes and I personally would be good to go, and not worry.
