qft,
Starting with the first low budget option, assuming you don't have a welder but do have an electric drill, locate a piece of 1/4" - 3/8" plate steel (Aluminum would work too but you have to go thicker for the same strength) say 5" x 10". Using your existing jack, mark four matching holes, drill and mount the plate to side of trailer tongue using your existing long bolts, nuts, and multi hole straps that came with the jack. Now you are left with a flat surface sticking up above your trailer tongue. Drill holes in the plate again to match the bolt pattern on your jack, get 4 new bolts, nuts, washers, etc. and bolt your jack to the plate. Bam, the pivot point of your jack is higher, therefore your jack will be able to swing down. Just to make it easier to visualize it, hook your trailer to the tow vehicle of choice, stand the loose jack next to the trailer tongue, and this will roughly tell you how tall the plate needs to be. Be sure to add a little more height to the plate to allow for vehicle sag, maybe a couple 2 x 4 under the jack foot just to take the math out of it. If you have access to a welder, the possibilities expand greatly, but the basic idea stays the same. Some may say that the plate sticking up will not be able to take the stress due to the added leverage, that is why I said1/4" - 3/8" thick (possibly even thicker since I do not know your particular details or situation) or even adding gussets, but this does work and I know from personal experience. I built a trailer for a friend that wanted to haul sack feed for his deer feeders and wanted to tow it behind his 4 wheeler - same problem as yours. This is not the only solution, but it is a very low buck solution.
Good luck, bentrotor
