I think that it really depends on you @Angrypuppy
... If you are mechanically inclined and reasonably fit, then it is no problem to do it yourself. I solo the Rush almost everytime. The front clamshell is the hardest to get on and off single handed, IF, you don't use the little dolly trick that a fellow owner came up with. It makes it a breeze and you don't have to lift anything. The advantage is that you usually don't have to remove the front during most track days. The rear shell is a touch heavy, but I easily lift it off every other session to lube the chain. Some others just jack up the back so they can see the chain and lube it without taking off the rear clamshell.
As for loading and unloading.. as others mentioned... buy a winch! I have never understood why anyone with a track car and trailer doesn't have a winch on their trailer. Stuff happens on track, and your car may not always be drivable. Plus it is a whole lot safer and easier to just hook up the winch versus driving it up. I have a ComeUp winch with a wireless remote, my brother has a Warn winch. For less than the cost of a set of tires, it is well worth it.
The key is setting up your trailer/rig for single person operation. It takes some time to do it right, but it is not impossible or even that hard.
Now it is NICE to have other rush drivers around on the weekend for any event. The reason is that you have someone else to play with (the rush are just WAY faster in the corners vs most all other cars) AND if something goes wrong you have another person to help or pick their brains. You also learn a whole lot how to properly maintain the car (also pick up new tricks to make it easier).
