How much weight goes in the caravan?

Bear in mind part of that 150Kg will be swallowed up by a battery and motormover, however many socks and shirts you put in the car.

And for future considerations the plated weight that you should be working to is the MTPLM, effectively the max gross of the caravan fully loaded & ready to go.  The MRO or lower weight is not the one that will be a reliable guide figure.

The Kerb weight of your car is also subject to some varaiation as different manufacturers apper to calculate it in different ways, mainly in respect of how much fuel the tank has in it. Some record with a full tank and others with less. Some with a driver & some not.  But in my case I always put the heaviest kit such as awnings etc in the car & not in the caravan.

Load the caravan carefully, - there is loads of advice available on that, but it is important to get the nose weight as close to the maximum permited for your car & van as possible.  Too much weight aft and a light nose weight = Instability!

The club provide advice on towing weights that you will find at the bottom of the page. Basically it is illegal to exceed the towing limit of the car and the advice is never exceed the kerb weight and for beginners try to get the caravan MTPLM down to about 85% of the cars kerb weight. If learning to tow I would stay at under 90% to begin with and I would not exceed 95%at all.
