Not exactly our rig, but pictures of the same models.
'06 GMC Sierra 2500HD ext. Cab, reg. Box in forest green. It's pretty, until someone keyed it *angry face*
ETA: fairly sure we're putting a goose neck hitch in it sometime soon.
2 horse straight haul with dressing/tack room and all the windows are open-able <3 7'6" tall so my horsey will go in it and there's a ramp in the back. You can also take out the mangers so it's great for long hauls - the horses can get their heads down to clear their lungs. We just rent it, but it's $15,000 trailer haha so $300 for a weekend is nothing in comparison.
