revering v50 d up slope

[krbilkey]

In last few months have had a towbar fitted.
Tows well caravan/car tralier with small car on
But when come to reversing both up a slope (not hill) the serpent belt smokes relaced first time and tesioner
The older car tralier has a lock off for anti reverse brakes and the caravan alko auto system.
I accept that there may be a problem with the brakes coming on but my mate and i both reverse the car tralier and he uses a older fiat van with no problems up the same slope (we both remove the car)
The caravan (750kg) was pushed back up grassy slope

WHY is the serpent belt burnning the tralier lighting rigs both diffrent i would think the clutch would smell or tralier tyres slide?

Any one any thoughts in this matter.

thanks krbilkey.
