Lots of misinfo here...
First off, DL76, you are either in Lot 74, which is the 12thMan lot R, or you are in lot 58. If you only pay $1500 for the season, then it is Lot 74.
Next, yes the Equestrian lot does not have full hookups, however, there are two lots that do: Olsen and Lot 58 have full hookups. Penberthy has power and water, but no sewer. To say there are only a few spots with plug in power is just wrong. There more with power than without. Also, I would say that Olsen and Penberthy are walkable. I have walked from Lot 58, but it also has it's own shuttle to the back side of Aggie Park.
Now, to help OP:
Other than posting on the Ticket Exchange forum, you can go here:
https://transport.tamu.edu/Parking/rvfootballres.aspxThat will direct you to the two RV Exchange sites. Check it regularly. Note that the seller only gets face value, but transportation gets another 25%. I am not sure if that is the case for the 12th Man exchange.
Aggie RV Park would be an option if you have a generator. I am not sure if it sells out now or not.
Good luck and happy hunting!
