[WhiteWolf McBride]

I just saw the smaller PQ-12 units, 20mm throw (even has limit-switches!) at $65 - they might do the trick.

Then I thought, mount 'em vertically, and you have remote Trailer legs! Not cheap though, at $65 each... (the Tamiya kit is $114 MSRP, and includes the 5th wheel control)
