Sunshine... welcome to the MOC family! It's a great group to belong to.
Now for the bad news....... to take a trailer to Reno in two weeks and to not already have reservations.... well, is not good. Reno always has some sort of major event or conference going on and their RV parks are usually booked anywhere from 2 months to a year in advance.
You'll need to start calling ASAP and see if anything has opened up for the dates you want to be there and if you do find something anywhere..... grab it! You can also ask each place that you call if they have a "waiting list" for the dates you want and get added onto it. I haven't stayed at any Reno campground but here's some to try:
Good Luck!
