We are currently towing a 1500kg caravan with a Subaru outback. We have very little weight in the caravan & heavy stuff in the boot. It’s ok, it could be more stable & very sensitive to nose weight. So, it is getting changed for something heavier soon though as we are planning overseas trips over the next few years.
IMO, you really want something with at least 1800kg kerb weight (makes the caravan approx 85%). I’m not aware of a practical, affordable estate that heavy.
We are fans of Jap cars. Having spoken to a few friendly German car specialists who maintain Tourags & similar, the maintenance costs are often significant.
We tested a CR-V and a D-max pickup recently. The CR-V was boring, but ticked slot of boxes.
The pickup will take bikes without needing a step ladder, and will carry kayaks & all the other clobber for an outdoor weekend easily & safely.
