A truck cap is low-maintenance, not no-maintenance. A few minutes now and then keeps it dry and working for years. This applies to any cap, not only ours, so it is worth reading even if yours came from somewhere else.
Seals are the whole game
Weather seals are what keep water out, and they are the first thing to age. Wipe them clean, keep them free of grit, and a light rubber-safe conditioner keeps them from drying and cracking. A hard, cracked seal is almost always the reason a bed starts getting wet.
Locks and keys
Salt air is hard on locks. A little dry lubricant in the cylinders once in a while keeps them from stiffening or seizing. Do it before a lock gets sticky, not after, because a seized lock on a loaded cap is a bad afternoon.
Glass and struts
Keep the glass and its channel clean so the seal seats properly, and watch the gas struts on lift-up doors and windows. When a strut starts letting the door drift down on its own, it is worn and cheap to replace. Swap it before it fails fully.
Catch a leak early
After a hard rain, glance inside. A little moisture at one corner is a seal telling you something now, while it is a five-minute fix, instead of later, when your gear is soaked. Early is always cheaper.
