I actually ended up getting a Wave 8. My "sportsmobile" is a 20 foot box truck. It's 8 feet wide and 8 feet tall and I use it to travel around snowboarding. So, I found the Wave 6 wasn't quite enough heat when it got down below 20 degrees. I would think the Wave 6 would be great for a Sprinter or regular size van.
I’ve been keeping my eyes open for one of these on the secondary market for months. Good price but the timing is a wee bit tight. How’s the shape of it? Has the heating element/pad been compromised? Thanks.
