Construction costs are currently skyrocketing

Yes and no. We picked out something like that for the move, a tarpaulin trailer of that size weighs around 2t gross weight and about 700 kilos empty. Then only my girlfriend is allowed to drive it, but with a 1.5t permissible trailer load we should be able to get the furniture in there. In a pinch, just slightly overloaded, because that would only be an administrative offense ;)

Really? I haven’t found anything like that. You could consider taking the B96 course, then you’re allowed to drive something like that with the smaller license.

Anyone who helps out with construction themselves should buy a Multicar. Three-way tipper, 3 tons payload and very maneuverable. Only 1.50 m wide.
Better than any trailer and much cheaper to buy. Getting materials from the quarry or hardware store, no problem.

I still have old delivery notes from the quarry in my Multicar. Sand 4.50€, frost protection gravel 6.50€, and paving grit 11 euros per ton.

You can tow a 3.5 ton trailer (mini excavator) with it and it drives at 50 km/h. Can be had with TÜV for 2000 euros.

It’s just a bit niche. But actually a good tip. I think you already gave it in your first user iteration.
I looked into it once but didn’t go through with it.
1. Not so easy to get in my area (around here every winter service has one of those, they probably buy everything up).
2. Too little cargo space, I am only allowed 3.5 overall, so no trailer can be attached.
3. I wouldn’t feel like driving 50 km/h to Szczecin and back.
So unfortunately not for me, but definitely something for others to consider.

B96 is almost as expensive as BE. However, it only takes one day and you cannot fail ;) If there is enough time, I would rather do BE than B96, especially with regard to the even higher weight of electric cars.

Yes, it's a matter of time. How much GVW do mid-range electric vehicles have? Surely not much more than 2t? My Zoe is under 2t...

Zoe is also a small car and 2 tons is already a lot. Most larger cars are also around 2.5 tons. Of course, there can still be technical improvements, but at the same time more weight can also be packed into the cars. I would roughly estimate about 400 kilos more than similarly sized combustion engines as a rule of thumb.

Yes, of course, they have to be heavier, but this is often compensated by smaller additional loads, so that it doesn't make too much of a difference. And I think that is also one reason why there are so many E-models for which trailer hitches are not even available as an option.

It is worthwhile, but only to a limited extent even for people who like to do things themselves. If I need 10 tons of gravel or 6 tons of lawn edging stones plus paving, I can either drive to the building materials dealer 5 or 3 times respectively... even with a simple distance of 10 km, that takes hours upon hours. Or I have the stuff delivered; a truck comes, dumps the stuff or places it down. That costs money, of course, but my time is not free either, and the car that I drive back and forth multiple times also costs money... not just fuel. The building materials dealer is also only open during normal weekday hours, so I would have to take vacation or overtime for that.

For our move with 45m³ over 150km, we paid just under 1,800 EUR in May 2020. Since I am only allowed to drive 3.5t, we would have needed at least 3 trips with a Sprinter... so 3 days of vehicle rental, loading in A in the morning with helpers, unloading in B in the afternoon with helpers. Some helpers would have had to commute for 3 days, which costs money again. And at least one cabinet always gets damaged in such a DIY-helper move, plus dents in the stairwell and new/old apartment...

Doing the work yourself is worthwhile, yes. But not if you waste the time transporting material, which the professionals can deliver in larger quantities much more cheaply.
