Lol ok I'll try.
Although I'm better at answering specific questions
You know it's an underfloor side caddy lift, is it the same as is in your van?
It was the first time I'd ever used one but it was fine getting in as you're facing into the van, I didn't much like getting out as I felt a bit nervous driving the chair out onto the lift not wanting to go to far and falling off the end, but at the same time knowing that if you don't go far enough you won't clear the van at the back as you descend, but I'm sure I'd get used to it quickly.
In the van there's plenty of space to position yourself either as driver or front passenger, depending on which seat has been removed (you could, of course remove both and have two wheelchairs side by side). Spacewise I found I could reverse out of the driving position far enough without hitting the rear seat array for my feet to clear anything at the front for easy access to the side lift to exit the van.
In the rear you have the standard back seats which can hold three people and through the rear door a nice boot, the luxury side entry allows you over having a ramp at the rear of the van.
You can have an optional electric rear door fitted, but it costs over £2500 as it's a GM Coachworks add on because Ford don't do one themselves (VW Caravelle electic rear door only costs about £600 because it's a standard add-on). I found I could manage the standard rear door, so didn't bother with electric.
Does that help?
