A camper won't last long on a road like you describe. Ruts, potholes, etc. could cause flexing and twisting that could damage the trailer. Bottoming out, scraping front or back also could cause damage. If you want access down roads as you describe, I'd sell the trailer and get a tent or a pick up slide-in camper.
