With your stated very little experience this isn’t something I would try, yes a horse can pull a lot more weight than they can carry with a wheeled cart. I.E. 1 horse pulling a wagon weighing roughly 1000lbs on a street with 6 adults and 2 kids, vs a horse carrying 125-225lbs comfortably of dead weight.
The thing is rough trails make it harder, uphill they have to pull, down hill they are the brakes as well, loose terrain, rocks, unless ur on the pavement Id cut the pulling weight in half. It also depends on length of pull, given breaks ETC.
Takes a lot to “train” a horse to drive (pull) I have done it, some horses do it fine others takes a lot to get them into it. Now you could buy a pre trained driving horse, but also remember it’s a full year commitment. You also need to worry about the horse in camp. Is the area ur going into have rules against wheeled vehicles?
