Tongue blocks

6x6 block screwed on a 12" square of plywood. It is very solid and stable.

I use Lego style Lynx Leveling Blocks with a 6" X 1" wood block on top for the tongue. Works good for me but my tongue weight is only about 250 lbs. However, these plastic blocks appear to be pretty rugged since I used to use them under the tires to level the trailer and never had one damaged. Now I use a BAL Leveler that both levels the trailer and acts as a wheel chock.

I built a wooden block when when we got our first travel trailer to provide enough lift to unhitch without any problems. My first 2 travel trailers, the tongue jack was just too short to lift high enough to unhitch. And if hitching, was not high enough to get the ball under the coupler.

I built a "temporary" block. It was just a trail-and-error experiment out of scrap treated lumber: 2 - 2x8's criss-cross 2 more 2x8's and then put single 2x8's on top of that, two layers deep, for a total of 4 layers.

A little heavy, so I drilled a some holes and attached a couple kitchen cabinet handles to each end (There again, it was scrap stuff I had around the house).

Well, here we are more than 11 years later and I'm still using the same block. I've considered building a new one. I've considered purchasing something else, but I've not found anything any better and since this pile of lumber works so well, .... well???.... why make another one?

If I need even more height, I can simply add a another board on top (If parked on a bad hill. And if parked on a hill flowing the other way, a single board works just fine.

Cinder or concrete blocks are not recommended, however, I have used cinder blocks before and never had a problem. But the wood is still best. It's solid, firm, and has no "give".

You may find something made of plastic, but you've got to consider all the weight being supported on that single post, and all that weight is focused to a single point of contact under it. YOU WANT something solid. I would never trust "anything" plastic under the tongue jack.

I also use wood under my stabilizer jacks too. People sing praises about Lynx block. I have a set. Wood is better.

If you are using wood, stick with it. If you have to, take several pieces and just stack them on top of each other. That way, you are not having to handle any one single heavy item. That's still more support than anything plastic can support.

I had to do some back-searching through my Photobucket images, but finally found a good picture of my "temporary" block that's lasted over 11 years now! This is our Springdale camper, not our current one.

I have also found the wooden block solution adds to stability. As I fully extend my jack, the front seems to sway, especially if the site is sloped nose down and the jack is fully extended. Having a wide base and extra height means the jack does not need to extend as much and it seems to me to be more stable than without.

Just a simple jack stand that you would use under a car.

A 4 x 4 is exactly 3 1/2". I'd suggest you cut a block of 4 x 4, paint it, and attach a rope with handle. It will look good and is easy to handle.

I use the Lynx Levelers under the tongue as well as the stabilizers. I do sometimes put a small piece of wood on top of it. But in 10 years of using them. None have broken, or deformed. And my tongue weight is in the 650 - 700lb range

I had a piece of leftover treated 2x8 that I cut into 5 12" sections then screwed them all together. I attached a length of nylon strap to it for a handle. It fits on the tongue right next to the battery when traveling.

I've been trailering for about 25 years now. When I first started I located a 4x6 of oak, and a 4x6 of Redwood. Both have lasted me for all this time. If I had my druthers, I'd have both of them out of Redwood... doesn't rot or splinter as bad as oak... and Redwood is half the weight of oak.
Just my .02. :)

Lynx levelers for me too.
