I use my Lynx blocks on the two tires that are not flat and a jack to lift the last tire clear of the ground. Need a combination of clearance under the wheel well (lift entire trailer) and countering the articulation in the suspension. I'm not a big fan of carrying one trick ponies in my storage, using the Lynx blocks I already carry for leveling the trailer seemed the best way to resolve the problem. I have successfully used both the jack from the truck and a small floor jack I carry when I know I am changing tires on the RZR. There isn't much load on the jack with the trailer lifted and I place it directly under the existing suspension mount to ensure I don't bend anything. I also leave the trailer hooked to my truck and install all normal wheel chocks on the side not impacted to ensure it's not going anywhere.
I've got it down to less than 30 minutes from the "OH S..." to resuming my drive.
