As above. Check everything on the caravan carefully as brakes and other important items are often neglected.
The official LR tow bar has a breakaway cable eyelet.
The FL1 will legally tow a caravan of that weight.
I do have one last fundamental question, the caravan I am looking to buy has the following on the chassis plate in relation to weight
MTPLM = 1500kg MIRO = 1312kg
MIRO=Mass In Running Order. This is the mass of the caravan as it left the manufacturers. It includes the original sized battery, gas tank and anything else the van was supplied with. In this case 1312 Kgs.
MTPLM = Maximum Technically Permissible Laden Mass, also known as User payload.
This is the maximum the van can weigh, which in this case gives user payload of 188 Kgs. So you can add up to 188 Kgs of luggage, crockery, food and so on into the van.
The other consideration is the car itself. You must not exceed it's total authorised mass when loaded (MAM) and the car's mass plus the caravan mass must not exceed the maximum train weight of the car. I'll use my 05 TD4 SE as an example here. My SE has a plated MAM (Maximum Authorized Mass) of 2080 Kgs and a maximum train weight (car + caravan) of 4080 Kgs.
Just to add to the confusion. The recommended maximum trailer (caravan) weight shouldn't exceed 85% of the kerb weight of the tow vehicle.
My TD4 has a kerb weight of 1640 Kgs. So 85% of 1640 works out as 1394 kgs.
So the recommended trailer weight for my FL1 is 82 Kgs greater than the 1312 Kgs MIRO if the caravan in question. So it would be perfectly acceptable to tow this with my FL1, even if the Freelander is fully loaded to its MAM.
You're FL1 might have a slightly different kerb weight, but you'll need to check that. This 85% is only a recommendation, published by the Caravan Club. However as you're new to towing, it's advisable to stick to it as closely as possible.
Hope this helps.
