Approximate Roadtrip cost?

[rob3000]

Hi there,

I'm 22, from the UK planning a roadtrip in an RV (roughly $2000 for a month) for next June but while it's easy to work out costs such as flights and RV rental other costs are more difficult, can anyone help me?

Our plan is to fly to Tennessee, then drive in a car to Denver, at which point we get the RV and do something along the lines of this route



We're obviously saving on hotel rooms because we have a bed with us, but how about food? Being from the UK, I can't really judge how much food would cost us at say, a walmart for a month, and campsites per night? I could work out gas thanks to an online calculator and that seems to be around $700 or so.

Any other costs I should take in to consideration?

Thanks for any help,

Rob.

EDIT: Should have added, there'll just be two of us. Do campsites charge per night or by vehicle?
