Thanks for the intel.
I hang out in a few RV groups and there's post after post of guys having their tandem or triple rv frame/axles aligned for $200 or so.
I guess Denver doesn't have the same market needs as other parts of the country. Maybe our roads ARE better and we all just complain too much about nothing. ;-)
Considering it's a single axle, and it seems there's not an abundance of trailer alignment shops, I guess I'll just keep putting on tires. Probably best if I have them remounted and rotate every year, even out the wear. I don't expect much more than 5 years or so out of them anyway.
