I have lived in a tent for more than 12 months , mainly a few months at a time . It is surprising how much body heat goes through the bed to the ground . When you get up put your hand underneath and check . Put one of those blue tarps under to stop the heat loss . Double is better . If you get a leak in the airbed , tip 1/3 of a cup of water in . Blow it up and shake it around , a wet spot will appear where the leak is . Mark with texta . Let the air out and allow to dry before putting a patch on . Nothing worse than the bed going down in the night . I never got on well with camp beds , hard to turn over .
I have found that when my weak 12 volt air pump stalls , then that is the pressure I want ! Potato sacks are also good to put under the bed and one at the entrance to the tent . Handy to stand on to get dressed if you have a low tent .
