Good website. Delivery prompt and correct.
Will purchase from Everything Caravans again.
Excellent service and speedy delivery.
Cable included, unexpected.
Great service Great people to do business with.
We purchased an Anderson hitch about five years ago having worn out our previous weight distribution hitch. We tow a 2.1 tonne caravan effortlessly, level and without any swaying. It’s quiet, lightweight and doesn’t need removal when reversing. Highly recommend
Item is a little expensive but worth it. Quiet when running (no annoying fans, great for caravan). Can switch from charger to power supply to run 12v appliances and view real time parameters via Victron connect app.
