Just a suggestion but like buying optics if you can be paitient wait and buy an enclosed trailer. I was looking at trailers way back when and borrowed a utility trailer to take my kids dirt bike racing, someone tried to steal the bikes in the parking lot of cracker barrel. After thinking long and hard I decided on a 24 ft car hauler enclosed. Worked out great as I could leave everything ready to go including tools and camp stuff. Same deal with the horse trailer, when I went from the 2 horse tent deal I saved up and bought my second and last trailer in a gooseneck 3 horse and life is soooo much better now, my camp and tack and water and everything needed is ready to go at all times minus animals and food.
I use the horse trailer for the dirtbikes, camping, horses, elk camp, deer camp, quad, you name it its ready to go. Like you said everything in an open trailer will get hammered on the road in, during the hunt etc etc. Also when the weather is bad you dont need an awning or tarps or anything, just hop in the trailer and relax.
I met a guy that had a small enclosed trailer all decked out like an rv, he had water tank, solar power, fold down bunks for 2 guys, awning on the side, pull out grill, heater.
