Extending Trailer Tongue

Extending Trailer Tongue - 06/12/20 06:04 PM

With the addition of the camper, I need to close a 21-24" gap as it extends off the back.

2 options.

1.) Superhitch and Super truss extender. $1200
2.) Extend the tongue of the trailer by adding a swing away bracket and a 18" section of steel. I'm guessing less than $250.

No need to extend wiring. No need to extend brake lines. Weld, bolt, paint.

What issues other than overall length do I need to worry about extending the tongue? On the camper board, it seemed to be met with some opposition.

Guess i'd shoot a email to the company that makes the swing away bracket & ask if what you intend to do fits with the product.

Concerned with capacity on the first one. I'm going to get the boat weighed, hopefully this weekend to know what I'm dealing with.

Didn't catch the weight rating.

Here are the specs for both the first extenders (24" and 34") from eTrailer. Personally, I wouldn't trust this--much more leverage on the extender and original hitch in all directions. Would prefer to see additional lateral and vertical support. Maybe two braces angled from the receiver to something on the hitch itself or any other location on the truck. Make like an "A." I have seen some very elaborately braced extenders and they look like they would hold up against most anything.

I'll be waiting to see how the weigh-in comes out. I think you will be surprised.

Funny, the specs specify weight distribution. I wonder how that gets hooked up.

Specs:

Application: 2-1/2" x 2-1/2" trailer hitch receivers
Receiver opening: 2" x 2"
Extension length:
24" From center of hitch pin hole furthest from edge to center of hitch pin hole
34" From center of hitch pin hole closest to edge to center of hitch pin hole

Weight capacity when used with 24" length:
Maximum gross trailer weight: 6,000 lbs
Maximum GTW when used with weight distribution: 8,000 lbs
Maximum tongue weight: 600 lbs
Maximum TW when used with weight distribution: 800 lbs

Weight capacity when used with 34" length:
Maximum gross trailer weight: 4,500 lbs
Maximum GTW when used with weight distribution: 6,000 lbs
Maximum tongue weight: 450 lbs
Maximum TW when used with weight distribution: 600 lbs
Limited lifetime warranty

I know I'm the resident BABC Cheapskate but I kinda look at things like this as what is the thing I'm towing and what would it cost to replace it if the cheaper version was not up to the job and failed somewhere down the road.

As an example, on Beachcomber the engine side of the generator went T.U. I had a choice of replacing just the engine and keeping the generator part for about $7K, or replacing the whole thing for $15K. If I did the cheapo version and only replaced the engine I'd have a new engine and a ~23 year old generator part.

Given the difficulty of getting the gen in and out, which involves a land based crane, removal of the cockpit bimini, etc., I did not want to have to do that job again. I went with replacing the whole gen with a new one. Sometimes even a Cheapskate has to step up to the plate.

I also think the hitch could become an issue. That is why I started down the road of a superhitch and a truss they sell. two bars, two chains makes it pretty stout. $1200 later and it should be.

Then I thought about extending the trailer. It would reduce the tongue weight on the truck which may be good or bad. The pivot point would be under the trailer which I would have to take into consideration as it perhaps would have to extend it further than 24" so the corner of the trailer doesn't catch the boat or trailer. Additionally, trying to back the camper into the storage unit may also be an issue. That may make me want a longer extension to minimize the back and forth between the storage yard and the Hopefully tomorrow I can take the camper to the storage yard and see how it fits into the doorway of the storage unit. Then drop the camper and take the boat to get it weighed.

Mother nature is not cooperating at all!

==============

get this one, take it to a sheet metal shop, have some 3/8 or 1/2" thick gussets made and welded on kinda as shown.

The lower gusset, have the front notched so it just fits under the receiver tube, this will prevent the tendency of the hitch tube to want to bend at the edge of the receiver tube. This will strengthen up the static weight capacity big time.

The side gusset probably isn't even necessary but what the hell.

Every bolt holding the receiver to the truck should have at least a 100,000# shear strength rating.

The thing already has a 6000# rating using the 24" span, this addition will at the least, guarantee that wink

--Should you decide to just extend the trailer tongue, just add a bottom gusset to whatever you choose to extend it with smile

Interesting idea FR. The receiver on the truck is such that you can't slide that kind of brace over the edge of it. It has a rolled lip that goes around the outside of the receiver tube.

I did talk to tiedown engineering about their weld on tongue hinge. It is rated at 8500lbs and assuming it is properly welded on it is an acceptable use for their hinge.

Next steps are to get the trailer weighed for both total weight and tongue weight. Then contact a local shop and see what I am looking for cost wise to determine if it is worth the savings to modify the trailer. They will need to weld on the hinge properly to the existing trailer and weld a 24" tube extension to the coupler side of the hinge. I'll have them drill the holes in the tube for the coupler to bolt to.

Lastly, I need to determine what the right extension length would be. If the trailer is still hitched 2' under the camper, how does the pivoting and do I need to extend longer than 2'?

The domino affect. Buy a camper, upgrade the truck suspension, upgrade the hitch or modify trailer, buy more gear for the camper, fill the camper up, buy a bigger camper, buy a bigger truck.

What would the effect of lengthening the tongue do for the tongue weight? Would you need to make other adjustments?

I don't know yet. Once I know the weights I will hopefully be able model the change in tongue weight to see what kind of impact it has. If it requires other changes than it is likely not worth it.

Re: Extending Trailer Tongue - 06/17/20 09:10 PM

And it all may be moot. There are several 12-15" options for extended ball mounts. That gets me halfway to my goal and maybe far enough to not need any other modification.

Re: Extending Trailer Tongue - 06/18/20 02:11 AM

That would definitely be an easier solution. Hopefully it works out

"If the trailer is still hitched 2' under the camper, how does the pivoting and do I need to extend longer than 2'?

Be sure to add whatever dimension would prevent the bow from going into the door of the camper as the back of the truck goes down--like getting into a driveway that has significant rise. Also, if you have bow rails that go up and maybe forward, the same is true. Another thought--if the bow is too close to the door of the camper, the door will not open, even if the rig is on level pavement.

I ordered this to try. It's a $75 gamble

If it works well, then I saved some $. If it doesn't, I'll eat some money on return shipping or sell it local.

It gets me 16 of the 21-24" I wanted. That's pretty close.

Of course, if the boat weights are over 6000/600 it won't matter.

Re: Extending Trailer Tongue - 06/20/20 11:29 PM

100 lbs over the rating on the long ball mount.

Gross trailer weight 6100lbs
Tongue weight 480 lbs.

Truck with camper, 3/4 tank of fuel, me and 2 boys.
Front Axle 4400
Rear Axle 5580

GAWR
Front 4670
Rear 6084.

I'm right at limits for gawr with the boat hitched.

My understanding is tongue weight would lighten a bit if I extended the tongue which may not be good. The tongue weight right now is just at the lower end of recommended %.

Seems like overload springs, a super hitch and a super hitch truss extension are likely in my future. The 15" extra long ball mount is only rated to 6000 lbs.

SB, I have never been a fan of pushing the limits when towing. Nothing is more exciting than having the trailer decide where you are going!

It sounds like you are on a good course!

Me neither.

I did buy a 24" super truss locally today. It was lightly used, is what we will need and was 170 less than new.

Missed out on the fast gun camper tie downs because the seller sold them out from under me when we were supposed to meet. Same seller as the truss.

I'll keep an eye out for the rest of the pieces to put this all together.

Took the camper out last night for the first time. We all came home alive.

Re: Extending Trailer Tongue - 07/01/20 01:07 PM

And then I find this.

It gets me super close and I am so tempted to try it. Not sure it is worth saving $400 to use this instead of just sucking it up and buying the superhitch.

Looks pretty good. Think i'd have to try it out & see. Could always send back if not satisfied.

I'm going to offload the camper this week and then do some test fits with the tailgate down and an existing extension I have to see if it works. If it does, it will allow me to find the hitch upgrade used from a local source vs buying new.
