    Has anyone fitted a tow bar to a 740 or similar? We have fitted a tow trust tow bar to our and have had a lot of ground clearance problems especially with our motorcycle trailer. Just wondered if anyone had any thoughts?

    Have heard about the problem on Bailey Facebook page got a Autograph 745 but no tow bar, but they are very low profile so ground clearance is shite.

    First of all is the towbar at the correct height?

    Info from Witter towbars.

    Secondly is the rear end dropping when you hitch the trailer, even if the nose weight is well within limits it could still push the rear end down a lot due to the overhang, if so you may need to fit air assist to the rear suspension.

    Can you post the height measurement of the ball in it's unhitched state? I have a towbar and bike rack fitted by Watling Engineers and although I don't plan to tow any time soon I can check the height of the ball without too much trouble (it's in the loft). :) It might show your bar to be a different height for some reason.

    I'll measure it in the morning. I think that the problem is that the overhang from the rear wheels to the tow bar is considerable? Nose weight is spot on to Bailey figure of 80kg so I don't think that there is any rear end dropping. The first time it ground out we were not even towing!

    you need to fit air assist suspension to the rear axle to lift the towball height

    Bit of a struggle but it overwinters better up there and I don't have to drain down. :LOL:

    Distance to the centre of the ball should be at least 350mm.

    If the height to the top of your ball is only 42mm I can see why you have a problem. :LOL: I jest.

    To the top of my ball is 400mm so if I ever tow I may face the same problem.

    This is an archive picture from Watling but my "loose" measurement is accurate.

    Yes missed the zeros off still imperial measurements in Derbyshire but still remains that grounds very easily the 740 has a larger overhang at the back compared to the 6 berth version 760 i seem to recall

    Assuming you mean 420mm to top of the towball and it's a 50mm ball (it will be) this gives you a height to centre of the ball of 420-25 = 395mm. As Lenny has stated above regulations stipulate that the centre of the ball should be between 350 and 420mm with the vehicle laden. I've always based this on the vehicle in it's laden state (excluding the trailer \ caravan hitched) to be on the safe side rather than an "arbitrary" MIRO given by the manufacturer. So, again assuming your vehicle is in it's laden state you are within the criteria.

    The same regulations state your trailer tow hitch should have a height between 385 - 455mm when laden. Is it?

    How much does the height drop when the trailer is coupled to the towbar?

    If the towbar \ trailer grounds and the fitter has positioned the towbar to it's maximum height there is very little you can do except try and stop the towball dropping so much. As stated previously you would have to fit spring assisters. Reduction of the tow hitch weight could assist a little but the lighter you make it the less stable the trailer becomes. I would suggest a maximum reduction of, say, 10kg.

    The above from my previous caravanning days with a sizeable twin axle.

    Thanks for your replies. We took it back to the manufacturer yesterday and they said that the install was not spot on. The beam was at a slight angle looking down and as the bracket is quite long a small amount out at the beam can be as much as an inch out at the end of the bracket. It was removed and reinstalled and we are going to give it a try on a trip to St Tropez next week. The 2015 Bailey is a very low design however and raising the ball height too much would cause us problems at the rear of the trailer.

    Believe there can be "fitting adjustments" up to a couple of inches dependent upon manufacturer to ensure final height is within tolerance.

    Is this site different to the Bailey owners forum?
    Not on Facebook but maybe worth a visit

    Ours is a 2015 Approach Autograph 740 and the tow bar is made by Tow Trust in Atherstone.

    Lillylo also check your engine battery in some boxer cabs they've put in a 680ah battery should be 950ah this is a Peugeot recall and you get it done under warranty with Peugeot nothing to do with Bailey.
