Aluminum trailer ramps

Im looking at 7 foot aluminum ramps for better approach angle for loading onto my trailer. There are many "brands" with very subtle differences but I assume many of them are either built in the same factory or at least to the same standards. Most rated at 6000# per pair, I'll only use them for my 3300# car and one axle at a time so really half that.

Im looking at 80-84" long and 14-15 wide. The reviews are mostly good but some have posted pictures that failed. My main question is anyone with experience with any specific ones? I was thinking Vevor since it is actually kind of a store with their own site and a one year warranty. Amazon has a great return policy but only for 30 days. And of the examples below, the more expensive ramps have a lower return rate but also one less cross support. Maybe they offer partial refunds to people that are unhappy to keep reviews high?

Here's a few I'm looking at:

Just spin the wheel, pick one, and test.  You could always have a block you slide under the middle of each one if you're really worried.   If they do fail they probably wont snap, just bow into a banana shape.  Could be the most worrisome point would be the piece that hooks over the edge of the trailer.

Personally I'd look at someplace like etrailer or similar sites where I could talk to real person for something like the ramps. 

If memory serves, Patrick just bought a set for the trailer he just built.  https://grassrootsmotorsports.com/forum/build-projects-and-project-cars/20-dove-tail-12k-trailer-build/241696/page1/

Looks like he found some Vevor ones that worked nicely.

My friend has a set of aluminum ramps he's been using with his Mustang for a couple years now.  I believe they came from HERE.  I'd stick to a reputable place other than Amazon that will back it up if you ever had issues.  I've been using eTrailer for many years.

In reply to wae :

That was a good read, he went Vevor and I'm leaning that way. Also gonna copy his great idea for ramp storage.

Hi mike.

7 months in the Vevor ramps are excellent. The harshest load was probably the tractor as far as lots of weight on a small point and there was zero deflection. I've been using them all summer, doing so again Saturday. Highly recommend them. 

I bought this set of these ATV ramps for my lightweight trailer. They did just fine loading my MK4 GTI and rally car given that only one axle is really on the ramp at any given time. Cheap and very lightweight. I had them mounted sideways on the trailer tongue.
