Come in a pair… have a set for enclosed trailer and a set for the shed on 2x10s, 5-6 ft long. You would likely need as long of lumber as you can fit and get a decent head of steam for a truck bed.
If you in and out of a truck, best bed is to get a skid or trailer and makenit stationary.
Thanks for the info. I’m more looking for a ramp to get the PW in the bed before I go out, and then out of the bed when my day is over. I have enough hose to leave the PW in the bed all day as I work, I just can’t leave it in the bed overnight at this point (no garage). I’ll check out Harbor Freight, thanks again
