Inner tents pretty much look after themselves they should not be waterproofed as this will impair their breathability. However all parts of the tent must be thoroughly dried before storing away in order to stop mildew taking hold. Cotton tents may take several days to dry completely. Do not use detergents to clean your tent, plain water and a brush should remove most dirt. Always take the time to practice pitching a new tent at home in fair weather and foul and at night!- before departure. Pack a small quantity of adhesive tape for running repairs.

All flysheets will eventually degrade as a result of exposure to UV light. to minimise damage, keep the tent packed away in a cool dark place when not in use. if pitching your tent in one location for more than two or three weeks consider covering the flysheet with a sheet of coloured plastic. Guyline will need adjusting after a heavy downpour in order to keep the flysheet taut.   Some nylon flysheets come with taped seems. Those that do not will need a proprietary sealant applied to all major seams in order to prevent water from penetrating through the stitch lines. Ensure that this is carried out in the dry, well ventilated area several days before departure in order to allow the sealant to cure.  tent flysheets (particularly those made from cotton)  can be periodically re- proofed to extend their useful life with a reproofing agent. consult your retailer for advice on the most appropriate sealant or reproofing agent for your tent.

Ensure that all groundsheet seams are sealed, Groundsheets are expensive to replace if ripped. much better then to place a piece of plastic sheeting or a dedicated nylon sheet that matches the floor shape under your tent. on particularly rough ground place your closed-cell foam mat under the groundsheet. In cold weather a piece of thin foam cut to fit the inside of the tent floor will create a warm carpet for the occupants to sit and sleep on.
 

Tent poles should be separated, wiped down with a clean cloth (especially if the poles have been exposed to salt air) and dried thoroughly before storing. if the poles are shock-corded pull them apart and lay them side-by-side so that the cord can be shortened/replaced if it loses its elasticity. carry a short length of metal piping of an appropriate diameter to tape over a section of pole if one becomes broken in use.  Occasionally spray the ends of metal poles (and door zips) with a silicone-based spray.

If you are towing a trailer tent, ensure that the hitch is properly connected, the snatch/brake cable is attached and that all lights are working. pack heavy items as close to the road and as near to the axle area as possible. lighter items - such as sleeping bags can go higher up on the roof rack but make sure they are in waterproof bags.
