Newbie 2018 3730FL

[davidhur]

Hello all,
We are brand new to the RV world. Picking up my new 3730FL Christmas Present tomorrow at Camping World and could use some advice from the experts. Given we are DirectTV customers we had the DTV dish installed, i also ordered the wireless back up camera system. Before i walk off the lot, what else should I make sure I purchase? Any help would be appreciated.

Thanks,

Newbie Fiver...
