My family and I have recently bought a combo trailer and can now take our horses out riding in places other than our pasture. We have multitudes of trails within 3 hours of our house and will do a lot of day trips but several overnighters as well. We have a 5th wheel camper as well and will take both to camp in when we go overnight or longer. We've considered a LQ trailer but we have 4 kids and like to do traveling other than with horses too so that is pretty much out of the questions.
I have done a lot of research on the areas we would start to ride in and won't be going to places that don't have water for the horses so I won't/shouldn't need to haul extra water for them. Other than their feed, what else do I need to pack for the horses or in general? Of course our camper is always packed with our essentials but is there anything extra I should plan to pack for trail riding that I normally wouldn't?
