    We have many good choices in A-frame trailer type tool boxes you can see on the linked page. These include plastic, aluminum and steel models from well-known makers like DeeZee. You can click on the specific size you prefer. For a lightweight plastic option we have DeeZee's 6-cubic-foot Specialty Series tool box # DZ91717P which measures 36 x 19-1/2 x 18-inches tall. Mounting hardware is included. Plastic boxes spare you worries about rust and they tend to make less noise too. This box...

  • Will Any Fifth Wheel Hitch Fit in Reese Mounting Rails on a 2008 Chevrolet Silverado 2500HD
    The Reese fifth wheel installation kits that are available for your 2008 Chevrolet Silverado 2500HD are the Reese Fifth Wheel Installation Kit, part # RP30035, which is a universal kit and the Reese Quick-Install Custom Base Rails and Installation Kit, part # RP50064-58, which is a custom install kit. Both installation kits will accept Curt, Draw-Tite, Hidden Hitch, Reese, Valley and Husky fifth wheel hitches. They will not work with any of the fifth wheel hitches that are designed...

  • Fifth Wheel Rail Compatibility Husky Versus Reese
    Husky and Reese fifth wheel hitches both use industry standard bed rails, so the Reese Hitch should be perfectly compatible with your existing Husky rails. I've provided a photo showing the slot spacing on Reese rails. You can compare that to the side to side and front to back dimensions between the hitch mounting tabs. To provide a bit of security, in the future you can use the # 6014 pins, the # RP58093 pull pin lock plates and some # 37DAT padlocks. Even one of the pull pin lock...

  • How to Lock the CE Smith Spare Tire Carrier
    You can lock your spare tire to the CE Smith Spare Tire Carrier # CE22007Z-11050-2. All you need to do is add the CE Smith Padlock Brackets for Spare Tire Carriers # CE26002Z-2 which will allow you to use a padlock, the Master Lock # 37DAT to lock your spare tire. These brackets simply thread onto the carrier so you can use the padlock to help secure the tire. I've added links to video reviews of both the carrier and brackets for you to check out.

  • Recommended Options To Securely Lock Cargo To 24x60 Curt Cargo Carrier for 2 Hitches
    For an option to use with your Curt Cargo Carrier, # C18153, I recommend using an enclosed box like the DeeZee Specialty Series Storage Box - Chest Style - Poly Plastic - 3.6 Cu Ft - Black, # DZ6535P. This box is 35" long x 14" wide x 13" tall, and will require locks like the Master Lock Shrouded Padlock, # 37DAT, along with a cable lock or permanent mounting solution. Another option is the etrailer Cargo Bag w/ Mounting Straps - Weatherproof - 20 cu ft - 59" x 24" x 24", # 988501,...

  • Recommended Cargo Carrier With Tool Box for Lockable Storage
    The 20x60 etrailer Cargo Carrier for 2" Hitches # e98874 has the capacity to handle many tool box options. The internal dimensions are 59-3/4 by 20 inches, so a chest style utility chest will be best. I recommend the DeeZee Hardware Series Truck Bed Toolbox - Steel # DZ8546SB which is 60 lbs or the Aluminum # DZ8546B which is 52 lbs. If you want to go with a poly plastic option for weight and size preference, you can use the DeeZee Specialty Series Storage Box # DZ6535P. This is...

  • Lock Actuating Coupler On Trailer To Truck
    For your trailer with adjustable ball # T43397007K to be locked to your truck while boating, I recommend the HITCH-LOCK Trailer Guard Coupler Lock by Dutton-Lainson # DL13980 along with the Master Lock Shrouded Padlock # 37DAT. This will work as long as you have a hitch lock on your ball mount like # 5201 so they can't just use your ball mount to take the locked trailer.

  • Latch and Hinge Recommendation For Converting Ramp Door to Swing Doors On Car Hauler
    To convert the ramp door on your Wells Cargo Car Hauler to swing or barn doors, you will need some hinges and a latch. A lockable latch like the Polar Hardware Cam-Action Door Latch Kit # 383200 is a great option. This system features a bridge-type hasp to help prevent accidental opening and ensures a safe latching action. The black vinyl grip on the handle makes for a nice, comfortable grip. This will require a 3/4 inch standard pipe which can be obtained at a local hardware store....

  • Coupler Lock to Protect a Boat Trailer Both at Home and at the Boat Ramp
    What you could use is the HITCH-LOCK, # DL13980. With the plate angled up, the trailer is protected from someone trying to hitch up to it. When towing a trailer with the plate angled down, it prevents someone from removing the hitch ball already in the coupler. It can be used with the trailer hooked up or not. You will need to use a pad lock like # 37DAT with this HITCH-LOCK. It is also zinc plated for corrosion resistance so it would be good for a boat trailer. For a lock that can be...

  • Lock for Ram Truck OEM Fifth Wheel Hitch
    The Ram OEM fifth wheel can be locked though there is not a specific lock designed for it. The Reese OEM 5th Wheel Hitch # RP30160 will need to be locked with a padlock such as the Master Lock Shrouded Padlock # 37DAT in the place where the pin and clip are at the handle.

  • Recommended Coupler Lock For Adjustable Ball Coupler
    The HITCH-LOCK Trailer Guard Coupler Lock by Dutton-Lainson # DL13980 is a great option for both keeping your trailer coupler locked in place and deterred from theft. You of course need an external padlock like the Master Lock Shrouded Padlock # 37DAT for this application. If you are just looking for a lock when the trailer is not coupled, I recommend the Trailer Coupler Lock - Gorilla Guard for 2" Couplers # 63228 or # 63227 in 2-5/16 inch.

  • Recommended Trailer Coupler Locks for Wide Coupler Security
    For your Atwood Channel Tongue Trailer Coupler 80060, I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # DT25013KA or Master Lock Heavy-Duty Coupler and Latch Lock Combo for 1-7/8", 2", 2-5/16" Couplers # 3784DAT are both good options. The latter doesn't have any restrictions of the width of the coupler.

  • Recommended Locks for Securing Trailer to Vehicle and Protecting Bikes
    Locking your trailer to your car can be done in a couple of different ways. You can use the Master Lock Hitch Receiver and Coupler Latch Lock Set - Padlock - 1-1/4" and 2" Hitches # 2848DAT to secure your ball mount and lock your coupler to the hitch ball. Another option is to use the HITCH-LOCK Trailer Guard Coupler Lock by Dutton-Lainson # DL13980 which secures under the coupler and ball mount and utilizes a padlock like the Master Lock Shrouded Padlock # 37DAT to secure the trailer...

  • Availability of Keyed Alike Padlocks and Trailer Coupler Lock Set
    The Master Lock Trailer Hitch Receiver Lock and Coupler Lock Set - 1-1/4" and 2" Hitches # 3794DAT does not offer an option to be keyed alike to other kits or individual parts. The Master Lock Shrouded Padlock # 37DAT does have the option to key alike multiple padlocks, however there is not an option available to have them match the # 3794DAT lock set. Unfortunately for keyed alike locks, the padlocks are your only option for your slide in ramps that I can find.

  • Changing a Trailer Ramp Door To Barn Doors On A 6x14 V-Nose Enclosed Trailer
    To create barn doors out of your ramp door, you will need hinges and a latch. I suggest a latch/lock system like the Universal Cam-Door Lock for Enclosed Trailers - 1" Keeper, # 383200. This will use a 3/4 inch diameter pipe that you'll have to get at a local hardware store, but the bridge-type keeper prevents accidental opening and ensures safe locking action. It will also allow you to use a separate lock like # 37DAT to secure your cargo. We will also need hinges similar to Strap...

  • Recommended Tool Box and Mounting Method for Installation on the Back of an RV
    You can use the linked page to see all tool chests that are generally suited to your application, but there are a few considerations for installing a tool chest on the back of an RV. First, you will have to have a sturdy rear bumper for part of the chest to rest on since the exterior surface of the RV will not be strong enough to handle its weight. You will also have to confirm that you can find and mount the box to structural elements inside the RV's outer skin. This is something to...

  • Chest Style Storage Box for Ford F-150 with 5th Wheel Hitch
    Since you have limited space in your short bed F-150 the storage box I suggest is the DeeZee Specialty Series Chest Style Storage Box # DZ6535P. This rigid and lightweight USA-made plastic box measures 35 long x 14 wide x 13 tall so it will fit your space and it has over 3-1/2 cubic feet of internal volume. The video that is linked for you will help show you all of its features. I recommend adding Shrouded Padlock # 37DAT for security and battery-powered motion-activated LED Light...

However, we offer Reese Pull Pin Lock Plates for 5th Wheel Trailer Hitches, part # RP58093 sold as a set of four, that can be used along with the Master Lock Shrouded Padlock # 37DAT. This lock can be ordered in keyed-alike multiples by selecting this option from the drop-down menu.

  • Can I Haul an Extension Ladder on the Pack'Em Ladder Rack for Exterior Side Wall of Trailer
    Yes, as long as the ladder is not wider than 6-1/4 inches it will work for an extension ladder. Keep in mind that the weight capacity is 75 lbs per ladder as well. Most 28 feet and 32 feet extension ladders fall under this weight limit. This ladder rack does come with bungee cords to secure the ladders to the rack, but to help deter theft I recommend using the RockyMounts SteelBraid Cable Lock # RKY3850 with the Master Lock Shrouded Padlock # 37DAT. The Padlock can be keyed alike if...

  • Recommended 5th Wheel Trailer Hitch for a 2011 Chevrolet Silverado 2500HD With 5th Wheel Prep
    It looks like the 2011 Silverado models have an increased fifth-wheel towing capacity, so I would recommend going with a hitch rated up to 20000lbs, to take advantage of the upgrades they have included on the new models. The Reese fifth-wheel hitch # RP30081 would be a good choice for your application, and this can be installed using custom fifth-wheel rail installation kit # RP50066-58, which will mount to the existing holes in your truck frame. Luckily, Chevy even made some changes...

  • A-Frame Toolbox for Aluma Trailer
    We likely have a toolbox which will work with your Aluma 548 trailer although A-Frame toolboxes are not made specifically to fit certain trailers so you will need to know the amount of room you have to fit the box. I do recommend going with a plastic toolbox for your aluminum in order to resist potential corrosion and the DeeZee Specialty Series Trailer Tongue Toolbox # DZ91717P would be a great option. It measures 36" long in the back, 18" long in the front, 19-1/2" wide, 17-3/4" tall...

    The HITCH-LOCK, # DL13980 does not have to be totally removed in order to hitch up to a trailer. With the plate angled up, the trailer is protected from someone trying to hitch up to it. When towing a trailer with the plate angled down, it prevents someone from removing the hitch ball already in the coupler. It can be used with the trailer hooked up or not.

  • Fifth Wheel Rail Hitch Pin To Fit The Reese Pull Pin Lock Plates # RP58093
    The Reese Pull Pin Lock Plates, part # RP58093 can be used on any 1/2 inch pull pin. It is installed in the cutout portion of the pin where the pin clip is normally installed. It is made to be locked with a padlock like the Master Lock Shrouded Padlock, part # 37DAT. The Hidden Hitch Fifth Wheel Hitch Replacement Pins and Clips, part # 6014, are the only pins I have and they are the only size pin that we use to attach our fifth wheel hitches to the base rails.

  • Can Tow Ready Hitch Pin #63254 be Used with Reese Bed Rails # 50082-58
    I do have a solution for you, but unfortunately the Tow Ready Base Rail Lock # TR63254 will not fit the Reese standard bed rails like what you have installed. Instead what you will want to do is use the Reese Pull Pin Lock Plates # RP58093 on a pin or pins that have a groove on the end like part # 6020PIN (or part # 6014 for 4). This will then allow you to add a lock like part # 37DAT. If you choose to go with 4 of them then you can just change the option for the locks to be keyed...

  • Do 5th Wheel Hitch Mounting Pins Have a Weight Rating
    A set of pins like # 6014 that hold a 5th wheel hitch to the truck bed base rails does not actually have a weight/strength rating. Since the pins do not really bear any weight they work fine for any 5th wheel hitch, from a 16K to a 24K. The same We also have Lock Plates # RP58093 that can be used with a padlock like # 37DAT to lock your 5th wheel hitch to the rails.

  • Recommended 5th Wheel Hitch for Towing with a 2018 Ford F-150 5-1/2 Bed
    Since you have the 5-1/2' bed on your 2018 Ford F-150 what you need to do is use a stationary 5th wheel hitch and replace the pin box on your trailer with a Sidewinder or 5th Airborne Premium with the Sidewinder. The 5th wheel hitch I recommend using is the Reese Select Plus 20K # RP30081 because it features a superior single-jaw for 360 degrees of king pin contact and the higher weight capacity so that you have a safety margin (be sure not to exceed the weight rating of your F-150)....
