I got the digital elevation meter from Camping World. VERY worthwile. Now, even if the trailer isn't perfectly level, you just crank it up till the meter reads the right elvation, and you point it the right direction and theres the signal.....takes 90sec. Before if I was Lucky, it would take several minutes,
sometimes so long I'd get frustrated and have to try later! I mounted it just aft of the A/C and have not had any problems....fooling around with a tripod and wires seemed a bit messy to me...
