Air and Wash Facilities

[MinnBob]

I'm new to rv travel and would like some advice on a couple of items. This would be for my truck and travel trailer.
1. Where do you find the best spots for checking and filling your tire air pressure?

2. Are there places while on the road to wash truck and RV?

Thanks for your input.

Currently in Dalhart, TX on way to Apache Junction. Anxious to leave this plummeting cold spell!!!

Only a few parks allow washing. Some have separate water lines only for washing or a central wash station.
I've washed in state & county parks w/o a problem.
Local car wash for truck.
Some DIY have outside lanes for larger rigs
I've also washed w 2 buckets in " no wash" parks and never had a problem.
After a few days in winter Wx traveling I frequently run through a Blue Beacon truck wash and have them wash MH and Toad... around $50.
Some report problems w truck washes but we have been pleased w the BB we use in Brunswick Ga.
Most no wash parks have local mobile wash services available... $ varies w locale & what they do...eg polish & wax

Thanks for info. I'll be getting to my park today and will see if anything available.
