As mentioned by previous posters the bigger the better.
But a lot depends on what type of camping you do and when you do it.
If you visit CC sites for example and use EHU all the time then Solar is not worth it.
My experiences are that if you use the MH in winter in this country then again unless you have a fair size array of panels then you will probably struggle.
If you just want to keep the batteries topped up in winter while the MH stands of the drive then get a 80W panel.
If you intend to wild camp and use a toaster, microwave and hair drier then you also need an inverter and the biggest set of panels you can afford and have space for.
I have been reading on solar panels and regulators recently and it would appear that it is worth considering a MPPT solar charge controller over a standard jobby, dont as me to explain ask Mr Google he seems to know everything.

Definitely worth looking at especially as the prices for MPPT regulators appear to be falling.
Most folks agree that you can get around 15% extra out of MPPT than a PWM controller. In the winter that can rise to 25% as the panels are more efficient in cold weather so if you use the MH in winter then its another reason to use MPPT
I have been doing some experimenting with my freestanding 90 watt solar panel while wilding in February.
On a sunny day I was getting 90% more output from the panel than when laid flat. If you are wilding in UK winters then you need to factor this efficiency into your plans if you have a fixed panel. To my mind, this is more important than the few percent difference between types of regulator.

As big as possible. I have 220watts of panels into 460ah of batteries connected through a MPPT regulator and today we had a grey sky and managed about 2.5A charge at maximum.
Having kids we use a lot of power with computer, games console, TV, satellite etc. So I doubled our battery bank to take us through coludy days.
