I would say a 70 series land curser ute(do you have them over their?)would most likely fit the bill but really any reliable V8 would be up to pulling that horse float.
I know what you mean im quite surprised that the trusty old is extinct in the states, i thought that you might not get Holden or fords Utes but i would of thought that Land Curser, Patrol, HiLux(the two utes in the bottom pic of my last post) and others would be over their.
All so.... do you put bulbars on your pickups?
Interesting The v8 70 Series Landcruiser is rated for 3500kg towing capacity or 7,700lbs making somewhat it comparable to our similarly equipped v8 gasoline 1/2 ton F150, Ram, Silverado in that respect. But surely you guys have something bigger for pulling car hauler, construction, hay, large boat, livestock or other really heavy trailers? That DRW Ford f350 Super Duity pictured above has a tow rating of 15,000lbs or 6,803kg
We do have similar vehicles to your last pic, my misunderstanding is that the term "UTE" denotes a
car based truck much like the aforementioned el-camino. Here they're referred to as a compact pickup and are sold with a bed rather than the cab chassis format that seems to be so popular in OZ
You'll see some brushguards but most are there for styling alone and aren't sturdy enough to prevent serious damage in case of a deer hit on the interstate, Of late I have noticed some trucking company running Australian style kangaroo catchers on semi trucks though
07 Chevy Colorado
Nissan frontier
Both these models are also available in 2dr and 2wd format other manufacturers offer similar models.
