I see this has morphed slightly, and that is fine with me. But to add a bit more on my personal decision to pursue a BP over the GN.
1. Price and availability, in this area, I have yet to find a dealer near me that has a GN on the lot, I had one spected out with a lead time of 8 weeks (maybe not bad but..) And the cost is ranging about 1500-2000 more, add on to that the cost to add the GN hitch and wiring to my truck and I'm pushing another $800
2. Truck is not factory equipped for a GN so hitch and wiring would have to added (no big deal labor-wise but cost of adding) see above
3. My truck would be the only one in the family equipped to pull the trailer and the other purpose of getting a new trailer is for others to use it too, I'm far more inclined to let someone borrow my trailer (although that has bittten me in the past), than to let them borrow my truck and trailer!
4. I don't see any long haul situations for me, I am not in the farming, grading, or construction business, this is a trailer for personal use to move my tractor to a friend or neighbors house, some hunting land, to my business, etc... for small fun tractor work, lol. Not saying I would NEVER take it more than an hour away but it's not likely.
Again I'm not trying to make a case for or against either GN or BP, hey if a GN comes along that is in my budget and is in stock I'd go for it, I just have some Spring projects coming up (that are sooner than 8 weeks) and it'd be nice to be able to safely haul with an appropriate sized trailer!
