Can I tow a trailer which weighs one and half tons that will have a TWO
ton vehicle on the bed of the trailer, The trailer is fully enclosed and
tri axle.
Do I legally have to have a TACHOGRAPH fitted.

This will Hire/Reward, (New Business)

I will be towing with a Mitsubishi Pajero 2.8 Exceed I know the petrol
will be heavy !

If ANYONE can give a answer please contact me ASAP. I will be extremely
grateful

Here's hoping someone out there can give a straightforward answer

Whatever the legalities, you would be sailing close to the wind and attract
the attention of new VOSA cars which are becoming more and more common.
But as no expert, just my own experiences with cars on trailers and
articulated lorries, I can think of a few good reasons for not doing it.
For a start, a general rule is that total weight of the trailer and load
should not exceed 85 % of the weight of the towing vehicle. A bit higher for
4x4's but even so, you are pushing it (ouch!).
If your trailer wheel hits a bump, it causes the tow hitch to be pitched to
one side with a certain amount of force. If the towing vehicle doesn't have
the bulk to soak up the jolt, the trailer then dictates which way you are
going. You start by snaking and if you stand on the ankers the trailer would
just push you round. Faster speed makes it worse as the bump give more
energy to the trailer.

Try manoeuvring a single axle trailer by hand - easy. Try a twin axle and
you have to push down on the tow hitch to get two wheels off the ground to
get it to turn. Imagine the work your Mitsy is trying to do to dominate 3.5
tonnes on 3 axles! It will always want to go it's own way and I wouldn't
risk it over any distance or at any speed. Your vehicle would get a better
ride on a 7.5 tonner anyway.
