I also had our Side rack plate installed, on KTM pannier rack, so I can carry Rotopax 1 gallon fuel cell. I used to do this on 690, and it worked perfectly. 1090 has more range than 690, but it can be thirsty off road. Not needed for this ride, as there are petrol stations nearby, but it worked great. Mounted this way, Rotopax is rock solid.
Oleg had our 1090/1190/1290 Top luggage rack on his bike, and Kriega US-10, perfect bag for spare tyres and tools. Bag was mounted using Kriega rack loops. Rack has pre-drilled and countersunk holes for rack loops, so this works great too.
