theres is a section in rave/ owner handbook. the car can tow a braked trailer up to 2950kg high range. adding that to the vehicle weight ( unladen with full tank of fuel 2171kgs ) gives maximum train weight of 5121kgs. but each axle has a maximum weight limit and if you are going away on holiday, your car could be full of stuff and people which would bring the maximum trailer weight down too
Not sure where you got that. Rememeber the version of RAVE going round is for the american market, may have different legislation.
The manufacturers towing weight information is stamped on a plate under the bonnet. It does not make any distinction for high range or low range or number of axles on the trailer.
You have a maximum tow weight of 3,500kg and a trailer nose weight of (IIRC) 150kg. There is an all up weight given but it will be the vehicle maximum gross weight of (again IIRC) 2,780kg + 3,500kg = 6,280kg with individual maximum weights given for the front and back axles. The sum of the allowable maximum axle weights will exceed the gross weight so you need to watch that (thats where the nose weight comes in).
So thats the manufacturers specification. You then need to look at each individual country's specific legislation. For instance in Ireland I think the maximum allowable weight on a single axle trailer is around 750kg. In Ireland there are distictions between 4wd and 2wd towing weights (important in selectable 4wd vehicles).
But bottom line the Rangie is specified for 3,500kg towing weight.
Incidentally the RRC had an allowable towing weight of 4,000kg if the trailer had independant brakes (air), 3,500kg for normal braked trailer.
