well, I have a permanent back injury, blew a disc way back in 1997, had surgery, blew it again in 98, had surgery, blew it and 2 more in 2011. They say I need multiple levels fused together, but don't want to do it because of the poor success rate of it and the fact it has a low rate of helping anyway.....
It's resulted in permanent nerve damage in my legs and back. I have a lot of trouble getting around some days, some days I can almost forget about it, until I do something I'm not supposed to do, or twist just wrong or step on a rock or, or, or........ LOL
I have a LOT of trouble with my legs, especially the left leg and foot. It's hard to get up and down the steps, which is why in another thread I said I won't stay in a site I have to raise the camper to level over 4", it's just too hard to get in. I have electric tongue jack, and use an electric drill to raise and lower the stabilizers. I don't do any heavy lifting (the lube thread where I mentioned my SIL helping me with my bearing repack job, this is why, he did the lifting and bending)
I've said all of that, to say this. Only you know what you can do and can't do. Only you know if the suffering you'll do will be outweighed by the pleasure of getting out to the campground. For me, some days man it's totally worth it with no doubts at all. Some days it's just not worth it at all.
good luck in your choices, I hope you'll find it's worth it, heck in reality, I hope you can get out and do it and not suffer at all
