The 36" ramps use aluminum for the decking and steel elsewhere, so not exactly heavy, but not light either. My 2001 RT/10 with factory ride height can clear these easily. 50" ramps are optional for maybe another $124 or so.

I'm careful about some stuff, so I used my Honda Accord for the initial lift. The function was flawless, and so it was Viper time next:

Here's the unit with the RT/10 on it and the Vette below.

I was impressed with the dealer/installer, Clay Cannady at Superior Auto Lift Equipment in Youngsville, NC. He runs basically a one-man (sometimes two) shop, and he knows his products, was careful with the install, very honest guy, and he was quick to call Quality with the problem with the rolling jack and get them to ship out a new pump. If I needed to do it all over again, I'd buy from Clay without hesitation.
