NHGatorGuy,
Welcome to TBN.
So many things come to mind on this.
Can you tell us more about your terrain (hills, mud, are you carrying loads up hill or down...)
If you already haven't done so, check out these threads.
RTV vs. Ranger vs. Rhino
and
Why the RTV?
and
Kawaski Mule -vs- RTV 900
There's many other threads in this forum discussing the various machines. Also do a search on HPX, both gas and diesel models.
To summarize some of the findings.
Rhino = fun/play machine.
RTV = work machine.
Land Pride = megabucks but great machine.
Most others fall somewhere between the Rhino and RTV.
Now, I'll inject my personal opinion. I have not tried all the different mfgrs so it will be a bit biased (towards the RTV).
I have the RTV and my primary purpose for purchasing was also to use it for firewood. Prior to the advent of the RTV, I was going to get the Ranger.
A couple things that made me change my mind.
As MSamson stated: "In terms of pulling, the Ranger and the Rhino were attached back to back. The Ranger 500 took off with the Rhino like nothing was there."
I haven't tried it but I believe it may be similar if the RTV and Ranger were strapped together. Again, my opinion, but for pure pulling power, I think the RTV would win, hands down. Many on this forum have strapped on a trailer in the 3-4000# (or more) range and have had no pulling problems.
For hauling in the cargo box, take as much wood as you can fit (some nice heavy maple logs or something). It'll probably end up being in the 1200-1300# range. The RTV won't notice it.
I love having the power steering and diesel engine. I would strongly recommend getting the hyd. lift dump box.
When going down hill, the tranny on the RTV will keep the speed as defined by the driver. It will not coast as many other machines will.
In mud, you'll want ATV type of tires on the RTV. The HDWS tires will struggle in just a few inches of mud. With ATV type, a few of us have had it up to (or over) the floorboard and still got through OK.
The RTV is probably one of the slowest UTV out there with a max speed of around 25mph. For my purposes, that's plenty. If your machine is 1/2 work, 1/2 play, you may find the RTV kind of a boring (although comfortable) ride.
I can't speak for the other UTV's, but depending on any options you want to add on, Kubota's options are pretty pricy. Aftermarket parts are being developed but there's not a lot out there since the RTV has only been around for less than a year.
