Adding a dedicated RV power plug. What would you do?

I have a sub panel in my garage and could add a 30 amp RV plug in 10 minutes if I wanted. I still haven't. 15 amps is plenty for home use. The most I run at home is the fridge and maybe the A/C just to keep it cool while I'm loading things. I definitely don't need 50 amps at my house for anything; even my air compressor and welder don't pull that even if both were running at full output at the same time.
