Do you carry a spare tire?

I have to go the Roadside Assistance way. At my age and my Lumbar disability I can't handle a 295/80 r 22.5. That's a 40" tire (diameter)! I don't even have the Super tools to take on a tire change. I watched them change my tires last month, they used a 12K lbs hydraulic Jack...Now where am I going to find one of those at a goooood price? The guy was about 6 ft tall and just to place the Jack his whole body disappeared under the rig. Now for the front tires it may get a lil easier, but with my back it's just a risk and challenge I don't want to take on. Plus we're retired, we got time...we'll get there when we get there. I drive my rig at 55-60 mph anyway, so time is not of the essence with us. I see TT and 5ers passing me up at 70mph all the time, swaying and oscillating all over the road, it's scary. Then the other class A's pass me up too. To each their own, We're retired and not in a hurry. LOL, life's not that serious anymore. If I had to get from point A to Point B in a certain time frame I Definitely would not have gotten an RV.
