Hello "Roadtrip America" community!

My name is Art and my dream is soon to come true!
Me and my girlfriend have been dreaming of going on a roadtrip in the USA. Finally we have managed to save enough money to afford it and nothing is going to stop us:)
Our plan is to arrive to the US somewhere around the 10th of August. We have 1 month time in the US, but technicaly 2 weeks, +/- a couple of days for the actual ROADTRIP!(I know it is not a lot)
We were thinking of starting our trip in Colorado and by August 25th-26th get to Reno, NV. We have only ONE stop that we plan to make along the way, it is in Santa Fe, NM. Our friends live there. Other than that, we would love to see some beautiful places, views(there are so many: Grand Canyon, Utah, Arizona, New Mexico's white sands,........aaaaaaaah) .....on the way to Reno. OH! Why Reno?! We are going to visit the most amazing festival "Burningman", from the 27th Aug to the 4th of Sept.(after the fest, we won't be able to handle the road anymore, i'm sure;)

This is our FIRST EVER roadtrip. We are super excited and want to make the most out of our time in America, as we both live in Moscow, Russia.
Now I have done some research and tried to set/find/come up with a good, interesting and not a complicated route, but everytime I end up with is HUGE milege(have to drive 10 hours a day, everyday) or pointless driving back and forth..... want to have some time to stop and embrace the beauty of it all. We want to see everything and I understand that it's impossible.......
We really need your help. No. We REALLY REALLY need your help and wisdom:)) to find the coolest route and places to visit in the USA.

As i mentioned it will be our first time and all your advice and tips and tricks will be extemely helpful!!!!(even if you think "oh, everyone knows about that":)
We still haven't found a good place to rent an RV from ONE WAY, neither what we MUST take with us on the road. Don't know if we can park anywhere we want, orthere are special places for that. It would be awesome to try to get away from crowds and people, but i don't know if you're aloud to do that on an RV....drive out somewhere in the wild and stop and just "BE".
And finally....(cuz I can go on forever, typing this letter. hehe) An RV roadtrip is done for the experience, for the beauty of it all. It is not the cheapest way to travel, in my opinion. But still, I'm sure that You, road trip lovers, over the years, have come up with ways and tricks to save money on the road. I would love to hear them.

Unconditional THANK YOU for your responce and help!
So happy I found you!
All the best!
