2.6kW at 240 volts will result in a running current of 10.8 amps.
On top of this, every time the compressor kicks in there will be a starting surge which can be up to five times the running current.

Certainly pushing 10A EHU very hard, for reasons mentioned above! I wouldn't be confident that it'd be sure to work!
Bigger problem perhaps is, it's going to have to be the ONLY electrical device you use! Battery charger/12v converter, lights, pumps etc. would likely be the straw that breaks the Camel's back!
Take it it's a standard domestic unit, all the dedicated caravan/MH units I've looked at are much lower powered to ensure they ARE usable on a camp EHU!

What does "PF of 1" mean please, as I would like to learn?
Power Factor i.e. efficiency

Power factor is the cosine of the phase angle between current and voltage. Power factor is an issue if it is a motor.
If current and voltage are not occurring at the same time only the in phase component of current can be used to calculate power.
Think about it as a horse towing a barge along a canal. The pull is not in the direction of the canal so the horse has to pull harder.
With DC:
current and voltage are always in phase so amps X volts = watts.
With AC:
amps X volts X power factor = watts.
Typically power factor for a motor will be 0.8 and starting current for single phase could be as high as 7 times full load current.
Electronic control can reduce starting current.

I have bought anAC unit to take to France but just noticed it uses 2.6KW. The campsites ehu is10 Amp. Do I have aproblem?
It should not be a problem. Remember that the 2.6kw is maximum and normally the start up consumption. Also an air con is controlled by a thermostat so will switch on and off.
We have stayed on sites in Spain where they are 4amp. We have a Truma Comfort air con. Fridge and hot water were switched to gas. Hot water was turned off during the day.

Better with roof mounted Truma aventa comfort which is designed to run on campsite electrics , only draws 4.2 amps and easily works on a 6 amp hookup

The 4.2 amp is probably maximum when heating used and unlikely that heating will be used.
