Thanks for the replies.
I'll poke around here a little more and see if I can find a 3500- they seems to be harder to find than a 2500, but appreciate the comments on the opportunity for long term trailer choices.
I was originally thinking of a propride hitch, but that was when I was considering a 1/2 truck- I'm hoping now an equalizer would still be ok. With the Canadian dollar the way it is, it would cost me $3k by the time I'm done with PP. I currently have an 1000/10000 equalizer which wouldn't work, but like how it has performed for the price
