I guess I will pop in here and give my
worth of nonsense advice.
I've probably had 8 different RV's in the past, and what I have done is just went to the boat shop or WalMart and got those 3-4 inch letters and stuck them on the back of the rig. I've had many QSO's from other hams who have passed me then gave a call on .52 simplex. It just seems to be the "channel of choice" for most guys who are traveling, in my opinion. I remember back afew years ago, we were coming thru Wyoming, and an England Trucker passed us, and we had a QSO for probably 100 miles before he outran my signal. And if you are traveling through a town, giving a call on .52 for info usually helps more than calling on a repeater. Alot of locals ignore others on repeaters except their clique buddies, whereas on simplex, they'll more than likely call you back, especially if asking for info. Again my
worth.
Here is my present "signage" on my RV now:
