^ Good post Jim....and good things to consider. A means to un-lock the rear differential is one change I would like on my new Honda Pioneer. In my situation it is not a deal breaker as I am primarilly on my hunting property.....but I still would like that feature in order to do less damage to turf.
(I'd likely opt for PS if it were available too.....but the Pioneer steering effort is "OK".)
I really like the size of the Pioneer, good load capacities - much like the deere.....and if I dont have enough room in my bed.....I always have a trailer available to get the job done. When it comes to top speed.....seems mid 40's is fast enough for me with a short WB vehilce like a UTV. Power seems adequate for my needs.
I didn't know I would like the 1/2 doors on the Pioneer. But they really increase safety and keep you cleaner when riding in mud. The Honda is a nice blend of trail and work machine.....IMO.
One other consideration tho.....in Minnesota the trails have some limits on CC's and weight. 800 cc's and 1500 lbs. My machine slips under the limits and can be ridden on the MN trails. A good thing.

Also, my machine fit perfectly on a five foot wide x ten foot long aluma trailer.....which I already owned.

Great for travel to nearby trails.
