pin jacks needed ?

Had a pin tripod. Changed it for landing gear stabilizers. Two minute set up for landing gear system, much longer with pin system and no lugging the tri or bi-pod around.

They also keep the Grand kids (and me) from hitting thier(and my)head on the pin.

Lighter trlr, larger occupants, yes.

They do very little to stabilize ur rig , the ultimate cure is the landing gear stab. arms. I have a tripod for sale.

Needed not really. I have a Bi-pod and will use it if the front is higher than usual, and I'm going to be set up for more than an overnighter. I'd rather have the cross arm type stabilizers between the two.

Our new 5th wheel has shorter, more stable landing gear and doesn't require any stabilization. Our older 5th had longer LG and there seemed to be a little "play" in the telescopic sections. Try it out, if it seems to wiggle a lot I would look at stabilizer bars that stay on the LG when you travel. Also, between-the-wheel expanding chocks help to stabilize.

I have a tripod that i use and it does help with the wiggle, you might want to look at all types of stabilizer equipment before buying anything. There are a lot of different systems out there. From mwhat i read on this forum some seem to work much better than others.

I use a tri-pod to get rid of some of the wiggle - does not get rid of all of it. Mine is made of steel - if you get one get an aluminum one - easier to handle.

I have a Bi pod which was a 2 legged pin stabilizer which really helped out with some of the wiggle you get up in the overhang area of many 5'ers. I don't use it anymore after I changed trailers. Current trailer has almost no wiggle. Mine looks just like This One . What kind of trailer are you purchasing? Randu

The tripod under the pin box is NOT a "jack", it is a stabilizer, and is not designed to support the front of the trailer, or a whole lot of weight for that matter. Many of us have found that cross arm style stabilizers on the front landing gear do a better job of removing the shake in the trailer as you walk about. They do not require storage, since they stay attached to the landing gear, and frame and are easier to set up. A good set will cost you a little more than the tripod, but are well worth the investment.
