2023 Touareg Aftermarket Twobar/Hitch

Hi everyone, looking for any advice or real world experience.

Im based in Ireland d and looking to pick up a 2023 or 2024 Touareg for towing a trailer and caravan.

Ideally I’d like to pick up one with the VW factory retractable towbar but not many on sale. Anyone have experience getting an aftermarket detachable one installed?

Just wanting to know if we need to factor in the things like cooling, vents or parking sensors?

Thanks in advance
