I definitely couldn’t have done it alone, nor could my husband. I had a look at some of the vclass videos on you tube and they were ok as the 3 seater bench folds in to a two seater and one seater. The horizon is a 3 seater with no gaps, so it has to go in and out as a three. Aside from weight (manual said 75kg), it’s an awkward shape to get in and out through the doors and helps to have an extra pair of hand when fixing back in so that one can hold the bench and the other check the fixings are the right place. How many seats do you need. You could potentially sell your seats and swap for the v class bench if that’s an option. The reason I wanted to take my seats out was because we needed to lift the rails and add inserts so that we could take 2 extra captain seats to use as a 7 seater occasionally. It’s easy enough to take the single seats in and out alone. They’re still a bit weighty but no too bad.
how many dogs do you have? If you push the bench as far forward as it goes the boot in the horizon is enormous.
