But I didn’t find anything in the search, so here’s the reference to a Kickstarter project that was started a few days ago. Just before, I’m not involved in any way, either with friends or financially, but only with the customer/supporter. Here’s the project:https://www.kickstarter.com/…/…rkupplung-fur-das-model-3-von-tesla It’s about retrofitting a trailer coupling on Model 3 or the trailer load of an already existing original A To increase HK to approx. 1,450 kg (from 910 kg or 1,000 kg) at 100 kg of support load. Probably also for performance models. For Early Birds (currently 7 remaining) there is the appropriate test report for increasing the trailer load of an already existing trailer coupling for 350 EUR. Or a complete AHK for retrofitting including all parts (without installation) for 1,150 EUR (there are already all the early birds away). The Kickstarter project is still running 28 days, the amount is almost reached.
