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,...
From that center one, we're looking at 1-1/2". Then from the one that's closest to the shackle. That's going to give us a measurement of 2-1/4". Now, if we take a measurement from the center of those hitch pinholes to the back of the shackle, the closest point, there, of the shackle . the closest pinhole to the shackle is going to be 1". That center one, right here up top, that's going to be 1-3/4, and to the very back pinhole, that's going to be about 2-1/2". Pretty simple installation. You'll need to determine which way you want this positioned in your hitch. Slide this piece into the receiver opening of the hitch and then secure it in your hitch using a hitch pin and clip or hitch lock. That's going to do it for today's look at part number BDW20239.
Today we're going to be taking a look at part number BDW20181. This is the Bulldog Big Dog Shackle. This is the huge oversize shackle that's going to give that truck a nice, big truck look. This portion right here is going to slide into your 2" by 2" trailer hitch receiver. It's going to be great for work trucks that use very large straps. It's going to feature an 1-1/2" diameter forged alloy steel shackle. It has a really nice zinc plating on it so it is going to stand up really well against rust and corrosion.
This is an amazing product, would recommend to anyone that wants to make their truck look like a beast, works great with all size tow straps, can get some serious work done, fits perfect with a traditional 2 inch hitch, 5/8s pin fits perfect, i recommend buying a locking pin with your purchase of this hook, Solid forged steel, all soild one piece, sturdy clamp, This hook is HUGE no joke, 25lbs!!! Could barely lift it off my porch, Great customer service, they reply to emails within hours. Overall very happy with my Bulldog Big Dog Tow Hook! 468278
Most people who are looking for a hitch will typically get one of three different types of hitches: shackle hitches, ball mount hitches, or receiver mount hitches. People who simply want to have the highest weight capacity will normally purchase a shackle hitch since they have impressive towing weight capacities. However, if you would prefer the design of a ball mount hitch or receiver mount hitch, they are all viable options which are equally as easy to use once they are installed.
Today, we're going to be taking a look at part number BDW20239. This is the Bulldog Winch 3/4" Shackle for 1-1/4" Hitches. This is designed to fit most Class I and Class II receivers. Now, when it comes to the capacity, we're looking at a 3500-lb working load limit or your vehicle's receiver capacity, so you'll want to go by whichever is lower. This is going to be great for recovery situations. Simply provides an attachment point for recovery strap. This piece is going to be the piece that mounts inside your hitch.
I honestly didn’t have too high of expectations when purchasing this product as the cost was a lot easier on the wallet than local farm supply stores. That being said, this thing has a beautiful fit and finish. The ability to have the shackle mounted sideways, keeps from damaging your rope from pinch points. This thing is a solid chunk of steel. I’m not entirely sure that it is possible to damage this hitch on a full size truck. The hitch pin or shackle will fail way before the receiver will. Make sure you use this thing as it is intended because if you manage to rip this off, it is going to take armor plating to stop this thing in a projectile state. It is SOLID! Also, buy a locking hitch pin. Someone would definitely steal this if they have the chance.
A Class 1 or Class 2 receiver has a 1-1/4” opening and is typically only used on cars for towing small trailers or supporting a bike rack. Class 3 and Class 4 receivers have a 2” opening. You'll find these on larger SUV's (the body-on-frame type, not crossovers,) and pickup trucks. A Class 3 receiver can handle up to 6,000 lbs (depending on design,) while a Class 4 can go up to 10,000 lbs. (Again, that's design-dependent.)
Both run all the way through the shank. That's designed so you can use it whether it's in the vertical or horizontal mounting position. You can install it inside your trailer hitch receiver just like this or you can flip it to this position here and still install it inside the same hitch. You can use it in either the horizontal or vertical position. The shackle is removable. This portion right here is just like a large screw.

This means that you should be cautious before you whip out the money that is truly required for getting a truck hitch. If you find a high-quality hitch that is anywhere between $20-50 many people might think that they are of a lower quality than what a local retailer has. However, the reality is that many local retailers purchase products like these and then mark up the price to local customers. Just keep in mind that the market is always subject to change and the price can rapidly evolve out of this range.

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.

Best of all, our hitches are easy to use. Simply pull the side pin and move your hitch up or down to accommodate where your trailer needs to ride. Your Rhino Hitch will be the envy of your friends wherever you go! Whether you’re at the lake, the dunes, the race track, or in the mountains, you can relax knowing that whatever you are towing will be kept safely behind your truck.
Solid, heavy, very thick coating. Look like they will hold up as advertized although I haven't had a chance to use them yet. Fit and finish is at least as good as higher-priced shackles I've seen at my local S&M Bondage store and I think they'll go well with that early 20th century farmhouse basement steam radiator theme or in any safe house as well. Finding chain and manacles to match might be a chore, but look around.
