I have had no trouble towing with my 4x4 Lab bumper. I have towed a BJ42 behind it for about 400 miles twice, with no problems. With the trailer it was probably 6,000 or so pounds. Although it was more weight than I would have liked to have towed, the SC'd 80 had no problems. I have also used it with U-Haul trailers without problems.
 
You may want to contact Octavio62 her on mud. He has a fab shop in east LA, built me a cutom bumper for 1/2 the price of the bolt on ones that is very beefy, has a tow hitch, has quarter protection etc.

Any pics? price range?

Thanks,
Paul
 
the Kaymar may not be as sexy as some of the more recent rock crawling designs but does well what it has been designed for: exped style wheeling/driving.
Now, it's not designed specifically for crawling, but can certainly handle it. There are reports of Kaymars doing the Rubicon and Moab without trouble. Although I'm sure you'd hit or scrape it more than a tucked in bumper requiring to cut off the cross-member.
It is rated for 7000 lbs towing, more than a type 3, and can be run with both a pintle and a receiver device at the same time.
Certainly not a bad choice for most folks out there.

I've just finished installing mine, relatively straight forward process, all bolt on. I wanted a dual carrier (tire and jerry can holder) that was rated to tow. I was hoping that Slee would manufacture a dual swing-out bumper for the 80 series like the latest design for the 100 series, which I love, but they currently have no plans to do so.

I may have still bought a Slee bumper except that they are not really designed to tow; those "hitches" that are shown on their site are meant for hanging bike carriers etc. Slee strongly advises against using them for anything else.

That said, customers regularly do otherwise, and from what I can tell, without trouble though I personally would not tow a loaded car hauler with a receiver that bolts to the bumper, or the "upgraded" Slee hitch that requires you cut a hole through the rear cross member/"bumper".

Unfortunately if you truly want a tow rated bumper, e9999 is right, there is no other bumper that accomplishes this from an "engineering" standpoint (the Kaymar has a capacity placard on it that exceeds the tow rating of the 80). He is also right about the Kaymar not being a crawling bumper, the corners are not contoured, and the hitch, which ends up hanging where a receiver hitch hangs, does cost a penalty in departure angle, though probably no more than any other bumper with a frame mounted receiver hitch installed that you should really have for pulling heavy loads.

Despite the Kaymar's apparent corner and below frame "bulkiness" it should be kept in mind that it fits tightly to the rear cross member, so it doesn't add any more overall length to the truck when compared to any other bumper that fits the same way.

From what I could tell the 4x4 Labs bumper offered the best in terms of being compact, but it requires the installer to cut the rear cross member out.

I guess you need to decide if you are prepared to pull with another bumper and have a better departure angle at the expense of the tow rating, or give up the departure angle and gain the tow rating. For safety's sake I went with the tow rating.

Happy bumper hunting...

While this may be correct, the OP needs to know that the swing outs will add overall length to your rig. For example, with my spare LT265/75-R16 mounted, add 11" to length. Other features may add more or less. This is important info when determining if your garage will handle the addional length.

I am looking at getting the new style Kaymar.

Can anyone tell me what is the biggest tire size their carrier will accept??

My spare is LT265/75-R16 as previously mentioned. There is an approx. 2" before it would start to cover the rear USPS taillight and 3" before it starts to interfere with the swingout bumper latch. I believe the swingout is stout enough to hold any tire that will fit. According to my tire calculator a LT315/75-R16 would not cover taillight. YMMV.

Sorry, wasn't trying to address the overall length question, missed the OP's original question, I was just clarifying the ground clearance issue...

I wondered about the max tire size as well, here's a thread that speaks to that, along with some of the other questions raised in this thread. The pic in the second thread is of a 35" tire, about the max that you would go before you start to get to a true obstruction of the lights...

My DIY 4x4 Labs rear bumper was under $500 and has a tow hitch. Love this bumper very sturdy and looks awesome.

Wow nice 80.
Do you happen to have pics of your rig with the swingouts in the closed position (side profile). It would be nice to see how far the tire and the ladder are from the lift glass/gate. I remember the tire was extended too far from the hatch to make it look awkward/funny looking - which turned off some to get something other than IPOR.

Thanks in advance.

They use the 4x4 Labs tire attachment now, which is adjustable, unlike their previous swing out. Also if you like the angled look versus the vertical look of your spare (can be requested either way) that will let you tuck it in even further.
 
IPOR

I purchased a used IPOR bumper from another mud member that already had a hitch and a single old style tire carrier and high lift mount. I had a minor problem with the tire vibrating forward and backwards on the freeway and on washboard roads. Upon inspection it was the entire swing mount to bumber base that was flexing at the end with the wing moving up and down slightly. I had a local shop weld up some side braces on the wings to the frame and all is fine now. Took a few good hits at Moab with no problems.
 
So I'm looking for a rear tire carrier bumper. I run my truck without mudflaps. I need to be able to occasionally tow a project car home on a U-Haul trailer. I would like an integrated hitch, as taking the factory one on and off for every tow job is getting quite annoying.

What you are doing now mounting the Draw-Tite is currently the safest way to do things. I think slee has the most stout and safe hitch out of all the aftermarket bumpers since his mounts to the frame with triangulated supports. But even Cristo doesn't recommend towing anything too heavy. Many of us believe that he is just covering his AR$E and that it is pleanty stout to tow a boat or a light trailer. But a triler and a vehicle would be pushing it IMHO.

I personally had my Hanna Bumper modified when I was refurbishing it to accept Slee's 2" hitch and plan to tow a light 18' travel trailer in the future so a plasma cutter to whatever bumper you choose and maybe chosse a bumper that maintains the rear cross member for additional strength.

Owned and towed with a Kaymar for years. I've also whacked the PS rear corner of the Kaymar on rocks too!

Kaymar is the only 'rated' bumper out there. Slee has the disclaimer on his site because as a small shop he just doesn't have the resources to get his towing solution rated. That being said, from pics I've seen of it on his site, it looks every bit as stout as the Kaymar is and I personally like the looks of his better! Kaymar has the advantage of a dual swingout if you want that. You also save on shipping. You only have a drive from Encino to Simi Valley! I'm fairly sure that SOCALFJ has 35's mounted on his Kaymar swingout - two of them. He's gone with dual tire swingouts as opposed to one tire and one jerrycan.
