I bought a new bailey cadiz with tyre pal fitted. Pressures were set at cold 19 deg  car front 38 rear 45 caravan 60. After 2 hours of mixed roads readings were car front 41 at 31deg rear 50 31deg  caravan 70 44deg. They all remained stable and each side
very close to each other. This has been repeated on several journeys.  The question being tyre pal recommend setting over pressure warning at 20% over ie. 72 for caravan.  Any comments or readings for comparison out thrre

    Recently  bought a tyre pal set up to use on our X Trail and Bailey Cadiz. Just back from 1000 miles of towing. Cold pressures were set at 41 front 38 rear and 60 for the van. Pressures generally increased by about 5 psi on the car and up to 9 psi on the
    van and were stable. 69 was 3 below the suggested alarm level so I was happy with this. As far as temps were concerned these varied as when we went away air temps were 6 degs and later on in the holiday over 20 degs. I adjusted the cold pressures to be correct
    at the ambient temp, therefore on cold days the car tyres were only reaching 17 and van low 20's, whilst on the hot days car mid 20's van mid to high 30's.

    The caravan tyres run hotter than the car, because a similar weight is carried by 2 x tyres on the van as opposed to 4 x tyres on the car.  The van has drum brakes too, which retain more heat than discs.  The fact that they are at 60psi to start with means
    that their pressure will increase more per degree centrigrade, so i wouldn't worry unduly about the readings.  The figures suggest that your tyres were cold inflated at -2 Centigrade (271 Kelvin), if that is the case they are perhaps a smidge high at 'cold'
    pressure (generally considered to be 15 degrees +/- 5 degrees)
