Where can you buy sturdy ramps that you can use to load a riding mower into the back of a truck?

You can also rent the ramps from Home Depot

I would check both Rural King and TSC websites to compare prices.....those are pretty big ramps and they're not cheap...it may be better to by a used small 4x6 trailer , since you can use a trailer for sooo much more things...that's what I did....also if there's a small hill nearby, put your tailgate down, back up to the hill and drive right into the truck

I'd call rual king, if not TSC
