Hi Sean
I am sure the following will cause some uproar because of the price but we use a Trail-A-Mate for jacking , levelling and as a Jockey wheel. It is not cheap, although we have special offers on at the moment.
You asked about a jacking point and there is none provided by the manufacturers of caravans and we believe there should be, similar to a car so there is no mistake where you lift your caravan from.
It is ok for people to suggest putting jacks under the axle where it is safe to lift without bending chassis but you can not always reach this point depending on the ground.
When you use a jack costing not too much money, the actually cost of the jack that you are lifting your not so cheap caravan always leave me very puzzled and you are putting yourself in danger by having to place it underneath the caravan in the first place and maybe activate it from a lying down or bending position. (not good for the back)
With regards to Green flag and other rescue services we too have them because there are times where it would be foolish to attempt to change wheels but I also believe that the man who comes to help should not be put in danger either.
There are also many times that caravanners wish to lift their caravans. To put them on winter wheels, to change the wheel because of wear, to level when on site, to work on the underside of the caravan, to lift the caravan to secure the new alko wheel clamp on double axles, to name but a few.
So to have a good, easy to use, safe lifting device is in my mind essential and one which doubles up as a Jockey wheel as well means you always have it with you.
None of us are getting any younger and it also means that if required I can also assist my husband in the operation as Trail-A-Mate is so easy to operate and it cannot fall off or away from the caravan even if you rock the caravan.
What ever you decide to purchase just be very careful when using it that you do not damage the chassis or yourself and find out exactly where to place it on the axle and how to use it.
Have a dry run at home before you need to use it in an emergency.
Hope you enjoy you new caravan and safe caravanning...Joyce
