Rear Bumper Supprt Brackets (Safety Struts)

[FedMill]

I added the ''Safety Strut Support Bracts'' to the rear of my 2600RB bumper. I had to drill holes thru the frame to enable the bolting of these brackets. I went above and beyond the instl directions, bought and used thru bolts all the way thru which I felt was better and stronger instl. They fit up nice and according to the manufacturer, they are suppose to add 400 lbs of cargo carrying capacity to the bumber ?? Now with that said, I do not intend to go anywhere close to that capacity. I am going to install a dual hitch steel cargo carrier that weighs approx 60 lbs. I then will carry my 55lb Honda Gen set, two five gallon cans of fuel and small misc stuff that I estimate will not exceed 200lbs at most.

I thought I would post this for others who may be wondering how to stiffen up there bumper,,,

I also added support brackets to the bumper on our 2600 RB. Then added a small Curt cargo carrier which I think weighs around 40 lbs. I also raised the spare tire carrier to get the tire above the side side rails of the cargo carrier. I then added a small brace to mitigate any wobble of the Curt carrier. I have a 62 lb Generac that I made a mounting bracket for that will go inside the cargo carrier along with a 2 1/2 gallon gas can.

Good idea on the tire, I’ll prolly do similar. My Aluminum Ultra Tow cargo carrier is on order. Rated for 500 LBS but it will only carry about 200 lbs at the max. My Honda 2200 Gen Set, two 5 ga cans of fuel and a portable fold-away ladder.

I moved the spare to under the frame and carried my Honda 2000 on the bumper in its place.

This is what I used on a 2800bh. Quick Products QP-SBSBU Standard RV Bumper Support Bracket https://www.amazon.com/dp/B081BM1CS...abc_GMT1FBADJVWKDHK9QDT9?_encoding=UTF8&psc=1

Those are what I used as well.

Are these brackets approved by Lippert to increase load capacity of the bumper?

I've been interested in these and was looking at the SafetyStruts brand website and they refer to pound-feet of capacity not straight pounds. It's all about how far away from the bumper the weight is being carried. They have a good explanation of this here https://mount-n-lock.com/pound-feet

It seems the Amazon knock-off parts are misleading when they say 400 lbs capacity. Do some measurements and calculations and be conservative!

I think if you re read our posts you'll see that we are both being very conservative on how much weight we are expecting the bumper to support.
I know in my case I will not be exceeding the original weight limit per GD. So the brackets, approved or not, are only backups.

Just wanted to point out for everyone else reading this thread that these brackets likely do not increase the load capacity of the tube bumper to 400 lbs as indicated in the description in the link to the Amazon product. The link about pound-feet is a good read and explains why bumpers get ripped off with relatively light loads.

What is GD's weight spec on these bumpers, I couldn't find it anywhere?

The manual says zero, but "urban legend" says 300 lbs.

The manual says zero, but "urban legend" says 300 lbs.

300 lbs. is for the frame-mounted hitch receivers for those units that come with one from the factory. The square tube bumpers would be nowhere close to that.

I need to check my manuals, brand new to RVing, but I'm now wondering if GD even supports the weight of the spare tire and its mount hanging on the bumper? Are the spares bumper mounted from GD, or mounted by the dealers? Assuming it's all factory installed/approved, hoping that's correct.

Thanks. Any known, approved weight load on that bumper/hose holder, aside from spare tire?
Have a good one!

Is the rear bumper referenced in the Owner's Manual somewhere? Just curious as I've read it quite a bit and don't remember seeing it.

Yes it is. I looked it up yesterday. Page 150 upper right.

I just installed those brackets on my 2600rb, I removed th spare and it’s new home is the truck bed. Used the horror freight small cargo carrier for my generac 3000i which is large enough to run my AC and only weighs 60 lbs

 

[2ACDogs]

Finally found it in my manual page 122 upper left. Says:

do not add items to the RV rear bumper blah blah blah.

And they put the spare on it.

Since these seem like a permanent addition to the RV a couple of short weld beads between the bumper and bracket might really seal the deal.

Dang I used those below, they were twice the price. I got ripped.

We purchased a hitch assembly fron camping world, had it welded by a welder who only works on trailers of all kinds, boat, horse, tt etc. He had a 7ft pry bar through the receiver tube to test his work. Said it was probably could for up to 700lbs but said to stick with the hitch welded weight listed of 350lbs - our cargo cage is good for 500lbs but well not test that. With generator and totes we sit at 295lbs

Lets add its welded to the frame
