Buy an old pair of channel-lock pliers at a yard sale and keep them in the utility compartment. Then you won’t have to remember to take them with you every time if you need to tighten the hose or unscrew a stuck sewer cap. They will rust so an occasional drop of lubricant helps. Buy a cheap cell phone belt carrier, use a hook-and-loop (Velcro) fastener, and hang your pliers from the compartment wall.
