My stock gunfighter is good for about an hour and a half before I start to hurt.
I just put on my solo seat I had done by Spencer "greatdaytoride". It is so nice, I had the gel put in it. I am looking forward to taking it on a long trip.
If I like this after a multi-day trip, I might have him do the gunfighter too, so I can take the very occasional passenger. You can't beat his prices, unless you can do it yourself.
