I have the exact same truck and trailer although 2011 model years and use a couple year old P2 from our previous truck and trailer and it works like a charm. Not to mention this trailer although bigger by 5 feet and heavier tows much better. Get the P2 same as the P3 just not as fancy of a display Enjoy
I too bought a P2 vs. the P3 and saved a few $$. For the extra money spend you really aren't getting anything more but a different display (far as I know). Save your money & get the P2. If you feel like you just gotta spend the money then go ahead and still get the P2 and send me the difference. Hey.., only $40 difference but I'll take it.
Wisdom is the right use of knowledge. To know is not to be wise. Many men know much, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.
