• What Do I Need to Replace My Bumper on My 2021 Lance 1475 to Attach a 27 Gallon Waste Water Tank?
  Hello Michael, Thanks for writing in. You’re not finding a 90 degree bracket because that style of connection isn’t used or recommended for your trailer. The rear wall plate on your Lance is not structural and is not designed to support cargo weight. Trying to tie a bumper into that plate would fail under the kind of load a 27 gallon waste tank creates. The correct solution is to mount the bumper directly to the frame, which is exactly how the Mount n Lock system is designed. For your...

• Should Loctite Be Used When Installing Mount-n-Lock SafetyStruts?
  Hello Chris, thanks for reaching out. Those self-tapping bolts are generally pretty secure, and if they are good and tight you shouldn't have problems with them backing you. That said, if you want to use loctite for added security you definitely can. Let me know if there is anything else I can do to help.

• Weight Rating of Mount-n-Lock SafetyStruts Standard RV Bumper Support Brackets
  Hey Chris, thanks for reaching out! The Mount-n-Lock SafetyStruts Standard RV Bumper Support Brackets # MO22FR can support up to 400 lbs of cargo and would allow you to use the full 350 lb tongue weight rating of a hitch receiver like the etrailer RV Bumper 2" Trailer Hitch Receiver # e38HR, provided your bumper can handle that much weight. You'll need to verify how much weight your bumper can handle from the manufacturer. If you don't already have a bike rack then I recommend going with...

• Will the Curt RV Bumper 2" Trailer Hitch Receiver E-100 Work To Pull a Trailer
  The Curt RV Bumper 2" Trailer Hitch Receiver part # E-100 which is a fit for a standard 4" x 4" rear bumpers will allow you to tow a trailer up to 3,500 lbs. However, that is what the hitch is rated for and the bumper could be rated for less (must confirm with manufacturer). If so, you could install supports, the Mount-n-Lock SafetyStruts Standard RV Bumper Support Brackets part # MO22FR or installs a frame mount hitch, the Adjustable Width Trailer Hitch Receiver for RVs part # 13703.

  Hey Matthew, the 24x40 etrailer Cargo Carrier for RV Bumper # e99050 that you referenced has a 500 lb capacity so it would easily handle the weight of a 220 lb generator. It would probably be a good idea to get the support brackets part # MO22FR but that depends on the weight capacity of the bumper on your RV.

• Can Mount-n-Lock SafetyStruts Standard Bumper Brackets Attach to C-Channel
  Hey Brian, in order to use the Mount-n-Lock SafetyStruts Standard Bumper Brackets # MO22FR on a C-channel frame you would need to have a welder box the frame where this needs to install so that it is able to attach properly. Otherwise it can't attach to an open C-channel properly. Are you using a bumper mounted carrier?

  Hey Pat, thanks for reaching out and the photos! The Mount-n-Lock SafetyStruts Standard RV Bumper Support Brackets # MO22FR looks like it will work on your application, but you'll need to more your rear jacks around to make more room, and cut off the welds to allow the brackets to fit.

• Recommendation For Increasing Strength of Rear Bumper Attached to Spacers Off Of Trailer Frame
  I do say those welds are bad and it appears the bumper is simply welded onto the back plate of the trailer rather than the frame. I recommend removing the entire bumper for the Mount-n-Lock Heavy-Haul'r Replacement RV Bumper # MNT43VR which you will then be able to add the Extensions # MO24VR. This will allow you to reach your frame and have bolts into the thicker frame material. The Mount-n-Lock SafetyStruts # MO22FR you found will help with the bumper attachment to the spacers the manufacturer...

• How to Determine If Swagman RV 2-Bike RV Bumper Mount Rack is Right For Your Application
  Many RV bumper manufacturers construct their product with a plastic cap or a hinged door instead of endcap, allowing bumper to be used for storage; apparently you have this type. Open that end piece to examine if the seam has spot welds (short welds at a number of separate points) or one continuous weld running the full length of the bumper; take note of the thickness of the metal while doing so. Some bumpers, frequently identified as heavy duty, will not have a weld seam at all but are...

• Can Two Sets of Mount-n-Lock SafetyStruts Standard RV Bumper Support Brackets Be Used on Same Bumper
  It's possible to use two sets of the Mount-n-Lock SafetyStruts Standard RV Bumper Support Brackets part # MO22FR but you might need to alter the hardware or instructions slightly. That said, it's not needed nor would it produce a higher capacity as the manufacturer does not test nor have they with two plates per side. If it gives you more peace of mind however then I say go for it. Thankfully, the owner of Mount-n-Lock is very cool when it comes to stuff like this and he even said himself...

• Comparing Mount-n-Lock SafetyStruts MO34VR and MO22FR
  I would be happy to help! The only difference between the Mount-n-Lock Safety Struts # MO34VR and # MO22FR you were looking at is the hardware used to attach them. The # MO34VR uses nuts and bolts where the # MO22FR uses self tapping screws. Since both have the same 400lb load rating I recommend going with the # MO22FR as it will be the easiest to install. This will allow you to use the Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" Bumpers - 3,500 lbs # UF35-946402 you were...
