Brakes are really important and also is
pulling power.
When we lived in the flat and hauled mostly in the
flat we used an 1997 f150 extra cab v8 automatic 4wd short bed and it did
ok to pull a two horse bp. But climbing hills it would bog down a bit and
even with the electronic brakes that we could manually adjust it really didn't
properly suit the type of hauling that we ended up doing.
We switched to a Ford 1 ton extra cab long
bed dsl 4wd stick (1999) and now have a gn exiss three horse and you don't
even know its pulling the trailer...stopping, no problem.
If you have a light duty vehicle such as a toyota
4runner you might want to consider a lighter trailer or even the brenerup as
some folks have suggested, but I really think it depends on your area (terrain)
and where you pull (terrain). We have friends that pull with a
Tacoma, and some that pull with Broncos and Escalades and they do just
fine. I think that one of the things to be mindful of is do you really
want to pull a large, heavy bp with a lighter duty suv or truck...especially
when going down a grade? Again depends on set up, how heavy the trailer is
and how light or heavy the towing vehicle is.
Haul your horses with the appropriate rig for your
safety and the safety of others. If you feel uncomfortable about your
current set up, follow your gut and change it.
