Jacking points on a Coachman twin axle caravan

Via an add strengthening steel support

So that is the bit of the chassis that you jack up on

You got it, not the chassis on any other poiint

I know as i do it all the time at home to get the Alko wheel lock on

I think the Op was looking at doing it on sites ,good luck with that

I don't know what happened to the post I put on here, yesterday.  It seems to have disappeared!  I have been using L 'n L on a TA van for the last six years or so and wouldn't have been without it.  In my opinion / experience, it's the only safe way to facilitate the fitting of twin Alko locks - especially on soft ground where I wouldn't want to be risking jacks of any sort.

I don't understand the fear of them puncturing.  On grass, it's never going to be a problem and on hard standings, I always used a length of industrial rubber matting to protect the air bag.  Plus - providing you make sure that the transfer valve is closed once the bags are inflated - even in the unlikely event of one bag getting a puncture, the other one's going to stay inflated, therefore supporting the van.

As for expense - less than the cost of staying on a CL for two weeks and as said above, a miniscule amount compared to the cost of the van.

I've had to move to the E&P hydraulic levelling system because of mobility problems which is the ultimate solution, but obviously, there's no point in suggesting that!

As I only have a single axle van it is a piece of cake using the lock on a site, because having all that room on a pitch you can get the lock and receiver lined up without using a jack.
