Thanks for everyone's comment and suggestions. I went ahead and got the P2 (from Amazon, overnight shipping) to get back on the road (get the TT home from dealer after a recall repair). The P2 worked as I remembered, so I must have run a Voyager, P2, and P3 thru-out my RVing life. I could not find my receipt for the purchase of the P3 11 months ago, so I sent eTrailer.com a message last night requesting a receipt. I received an email this morning with the receipt. I have called Horizon Global twice today for warranty service on the P3. After waiting for 10-15 minute each time I hung up. I have an address for the snail mail route, so I will try it. I figure if I get the P3 repaired, I will either go back to it or have it as a back-up unit.
