I'm working on buying a gooseneck trailer of some sort, and have been weighing the relative merits of trailering my two horses (who get along fine) either tied or loose in an open stock trailer. The reasons I like this idea are:
1. Stock trailers are pretty simple: the ones that I've found are generally cheaper, in better shape for the money, have fewer moving parts to go wrong, etc., and are more open and airy for hot months when we trailer most and
2. They tend to have side ramps, which is a feature I *really* want.
We live in WV where pretty steep HILLS happen. We only trail ride: no showing. When we camp, we use a tent for us and only choose to go to places with paddocks for the horses. So, we don't need living quarters, though the gooseneck will be nice if it pours while we camp, so our air mattress will be there for inclement weather. We don't go far; our typical haul is about 15-20 minutes, and our longest haul is about 1.25 hours. But: every mile is up and down, or around curves (some are hairpin).
Question for those of you who like/regularly trailer without partitions: do horses need the support that partitions provide if the terrain isn't flat? (Seems like most of those who post about trailering in open stock trailers live out West, where land is flatter, and roads are straighter.
