If your truck is a short bed then I'd opt for the Pullrite Superglide auto sliding hitch. The entire hitch comes out easily using pins so no need to unbolt anything. No tools required for removal or re-installation. The head assembly comes off separate making it easy for one person. Mounting rails are under the bed. Everything else comes out, slide rails and all leaving your bed completely clean.
One method of removing easily is to simply pull the bottom pins while your 5'er is hitched up. Then lift the trailer leaving the hitch on the king pin.
