				Hopefully I can dig that out. It depends what the tyres sizes are... ? 
What is the camper spec.

 Most seem to think this.Thanx for your help.

				44.1 Front; 54.39 Spare: 54.39 Rear
Cross-check with Simon's Brickyard here:

those 185 R14 C's do run high pressures

				Ta! Must get more air in a.s.a.p.!!No wonder the steerings heavy we thought it was due to our other cars having power steering but I suppose it helps if you've got the correct tyre inflation!!!!Oh well I live and learn.Thanx again your a star.

				Maybe small adjustments front to rear depending on load front/rear and whether you'd rather understeer off the road or oversteer into the nearest hedge  
 
 
If the tail's wagging the dog (big load in the back, oversteering), then a pound or two up at the back or down at the front . Conversely if she's understeering, vice versa.
Just double check the sidewall for max press. to be on the safe side - all pukka tyres should have a figure there somewhere.
NB. Check weekly or monthly, it's amazing how tyres can go down gradually without actually having punctures  
 
Update: Nitrogen fills are becoming more common. One of their benefits is 'supposedly) to reduce the speed of slow leaks over time
