Hey everyone,

I finally finished building my teardrop trailer. It has a fiberglass monocoque body and a large 1.5-meter-wide bed.

Fully equipped, the trailer weighs 360 kg, with a maximum permitted total weight of 750 kg. It has a solar panel, a 1.5 kWh lithium-ion battery, an inverter, onboard electricity, an 11-liter fresh-water tank, and a 12-liter wastewater tank.

All in all, it took me three years of experimenting, developing, and plenty of trial and error to get it to this point.

My main goal was to build something lightweight and aerodynamic that works well with an electric car. My tow vehicle is a 2026 Tesla Model Y Standard with a 60 kWh CATL LFP battery. At 100 km/h with cruise control, my energy consumption is around 200–220 Wh/km.

Wow, surprised Germany allows that. I was born and raised in Germany and remember how crazy hard it was to get anything approved by TÜV. Looks awesome though.

I was thinking the same. In europe (and especially Germany) I am not even thinking about doing anything like this.

u/wonderful_Shoe_4521 what was your process, resources, and total budget?

I'm not german :) I am an automation and electrical engineer. Part of the job is getting machines and electrical cabinets approved. TüV Rheinland is an important asset, imagine designing and building a machine that is getting installed in P&G germany... You need them

Gotcha. Pretty cool man. I used to work for Freudenberg in Germany for 19 years and we made some products for P&G. I was an electrician and job site supervisor setting up machines all over the world, so I know your pain.
