My 2 post lift is rated for 7,000 lbs. and was built in the US and is very well made . My concrete floor was specifically poured with the 2 post in mind . But my diesel dually truck weighs over 7300 pounds per the counties waste management scale and I just don't feel comfortable " pushing the limit " . This truck has been drop dead reliable so my main maintenance is oil/filter changes .
Even though it is a 4x4 I struggle to get my .............. ahem ........... manly shape

under the truck . So I am thinking about some ramps . Doing a quick search online there are basically plastic and steel . I found a disturbing amount of negative reviews on the plastic one's with the main complaints deforming or cracking

Back in the 60's and 70's I used the standard red metal ramps on a variety of vehicles with no issues .
I could also just build a set out of 2x10's or 2x12's and be rock solid . So how about some comments/pics on what you are using ? An additional 5 " - 6 " would be sufficient ( that's what she said

) but a little more wouldn't hurt either . On local Craigslist I see plenty of the plain Jane metal ramps for 20 bucks or so but the sticker with the weight ratings are generally long gone

. But only lifting the front so is a " standard " set rated for 2 tons sufficient ?
