I have used both; The ALKO one caused a lot of problems, actuating tuning left around corners, had to be disconnected to reverse park, had to be disconnected to travel on gravel roads - ALKO Technicians unable to rectify faults.
Have Dexter unit currently, great unit no need to disconnect to travel on gravel or reverse park.
Chalk and cheese units - I believe ALKO purchased the rights to Dexter in order to remedy faults in their unit - Having dealt with ALKO for service I would never again buy their product, even if it is a re-badged Dexter.

Welcome to the gang Ray, enjoy here and out in the playground.
Sorry, I can't help with your question but for what it's worth,
I have a 20' 2.7t aluminium teepee that tows exceptionally well without ASU but only tow no more that 90kmh at most. I am fully aware of sway so have my whits about me at all times. I am not saying nothing will happen because you just never know. So far so good for me.
Keep Safe out there.

Thanks for your response. I have just talked to an independent caravan sales and repair yard and they are authorised to fit both. However have been informed most people are now fitting Dexter.
