20 kg strapped onto the rear rack will be tough for any wheel, IMHO. Use front panniers for the majority of weight and the rear for the bulkier items. A trailer is also a viable option. Carrying or towing less weight is an even better option.

I'll be putting the heavier stuff up front and as I mentioned the 20kg is a worst case estimate. Likely one rear pannier is going to handle sleeping stuff, the second pannier is going to take clothes and the rackbag is taking half of the tent and all of my medical supplies (1000 syringe needles for one, there's other stuff as well)
