While it is good to have a D ring receive hitch in your Jeep just in case, it is always preferable to avoid a nasty situation in the first place. You should avoid driving in unknown areas or driving over something with an uncertain depth. You also need to drive slowly when possible. However, even the most careful drivers may end up stuck in the mud at one point or another. A D ring hitch is useful, but it is also good if you always carry a first aid kit, jack and shovel in your Jeep, too.
Mile Marker comes in at spot number three because of its cool orange color and multi hole configuration. Its prolly the most expensive on this list, with the same features and towing capacity as the others. It has a 11,000 pound working load. And you can insert the hitch two different ways, which will make your d ring shackle go vertical or horizontal. A cool added feature to help you get out of a sticky situation. Made for 2″ receiver and 3/4″ d-ring like the others.
We're going to take a measurement of the overall length, basically measuring from very back to very front. We're looking at about 8". If we take a measurement from the center of the hitch pin holes to the back of the shank . so measuring from this one right here to the back of the shank, that's going to give us a measurement. It's going to be 13/16 of an inch.
If you want a shackle hitch that can pull impressive weight loads with ease, then this should be one of your top options. With an towing weight capacity of 4-3/4 tons, many people simply won’t even need to pull this much weight. However, being prepared for the worst is better than no preparation at all. This is one of the reasons why many people will get a top-quality truck hitch like this one which boasts a considerably high towing weight capacity.
For your 2004 Chevy Avalanche the Rhino Rack roof rack part numbers # RREB137B, # RRRLKVA, # RREB-FK1 and # DK227 has been confirmed as a fit and would work well. Your sunroof wouldn't be an issue either. I would recommend keeping it closed since it will be very loud transporting a ladder up there from the wind noise. However, I have a better solution for you in terms of a roof rack for securing a ladder. Instead I would recommend the Rhino Rack HD bar roof rack part numbers # RB1375,...
Smittybilt is a decent brand. They just take generic things and put their name on them and mark them up in price. Their D rings are no different than any others you'd find on Amazon. My buddy put some on his XJ Jeep and the red powdercoat they used was evidently just an epoxy or something else not UV-stable, and faded to pink in a short time. He bought generic replacements for them and they were identical to the Smittybilt.
