I would get your bathroom scales then a piece of wood and lower the nose (hitch) so its in the towing position (level) and see what the weight is in KGs it should not be more than 50kgs for most cars
The tip when reversing a trailer is not to over compensate on the steering. Even the slightest turn on the steering will affect the way the trailer behaves. You have to think *wrong lock* i.e. the opposite direction to which you normally reverse your car.
It's almost impossible to teach anybody to reverse a trailer. I've been an HGV driver for 40 years and never managed it yet. You'll have to(likemyself) teach yourself by trial and error. Some trailers have what looks like two tennis balls on sticks at the two front corners of the trailer, this is so that you can observe what the trailer is doing because you can't see the trailer.
One last thing about your arrival on site with a trailer..... dont go too fast into the campsite... most of them now have speed ramps and your trailer will not like jumping up in the air about 2 feet and landing rather heavy.. enjoy..
Breynia's other half here; can we put all the 'excess baggage' [awning, fold up picnic table etc] at the back of the caravan to 'counterbalance' the nose weight, or is this a no no? Noseweight currently 55 Kilos.
Dont worry about it ,you wont even know its there ,its not like towing a shed!
Actually we DO feel the shed, er, caravan being towed; kinda tugs like a dog that's pulling on the lead, or 'undulates'. We have a Compass Omega 360/2 1987 vintage, and a 2 litre Landrover Freelander.
