Packages Designed To Be SAFE and EASY

You worked hard. Your travels should be Safe & Easy — from the order to the first hookup.

One order. The parts a first-time flat-tow customer used to hunt across four product pages. Vehicle-specific baseplate, Avail tow bar, wiring, coiled cord, keyed-alike locks, and a tow bar cover — matched and ready. Add a supplemental brake in Options and the order ships in four boxes instead of three.

What ships in the 3 boxes

BOX 1

Baseplate BX4104

Standard-tab plate for the 2006–2010 Hummer H3 (Works with Factory Brush Guard Option). Bolts to the chassis. No welding. Hardware and instructions in the carton. Tabs stay on the plate when you are not towing.

BOX 2

Avail tow bar BX7421

Class IV bar. 10,000 lb. 2" receiver in this package. Metamorphic Rock finish. Self-aligning steel. Folds and stores on the coach. Safety cables included with the bar.

BOX 3

Kit BX88464

7-to-6 coiled cable, 3-lock keyed-alike set, 4-diode tail-light wiring, and a tow bar cover. The pieces people forget until the night before a trip.

Three factory-sealed cartons. Add a Patriot in Options and we ship a 4th carton. The brake is not in this package price on purpose — pick it here, at the package price, instead of as a separate item.

Five things every flat-tow setup needs

Steps 1–4 are in this package. Step 5 is required by law in most states and provinces. Add the Patriot under Add a Brake in Options on this page — that is the package price.

Why should I buy from RV Camp Champ?

Looking for a reason? The unfiltered reviews below are from adventurers like Dieter — not a marketing script. Most stores sell a bar and hope you picked the right plate. We assemble the complete package for the person who does not want to become a parts expert overnight.

Good companies can sell. Great companies handle problems with the same energy or more.

The Avail tow bar — BX7421

Avail is the premium Blue Ox bar. All-steel, 10,000 lb Class IV, made in the USA, 3-year warranty. Self-aligning so you are not fighting the arms on a slope. Non-binding release levers and offset triple lugs so unhooking on uneven ground does not turn into a wrestling match. No centering pin, so it folds and stores on the back of the coach. Rubber boots keep road grime out of the legs. Safety cables come with the bar. This package ships the 2" receiver. Avail also comes in 2.5" at the same price — pick that in Options when it is offered on this page.

Avail is the step up from Alpha. Extra capacity, current Avail arms, and the 2.5" receiver choice at no extra cost. Alpha is still the right bar when the toad is well under 8,500 lb and the coach hitch is 2". Same plate either way.

The toad’s loaded weight must stay under 10,000 lb, and each safety cable must be rated for that weight. Match the motorhome hitch, chassis rating, and braking capacity to the combination — not just the bar. If the coach hitch is 2.5", pick the 2.5" Avail in Options instead of using a reducer.

The baseplate your bar hooks to

THIS PACKAGE: STANDARD TAB

BX4104 is a Standard Tab plate. Fixed arms stay on the plate. Simple, stout hookup. Blue Ox builds one style per vehicle — you do not choose the other tab style on this application. Absolutely no welding. Factory holes where Blue Ox designed them. Most of these plates take about 2 to 4 hours.

Fit notes for this plate

Application: 2006–2010 Hummer H3.
Blue Ox part: BX4104.
Tab: Standard Tab.
Fits: Works with Factory Brush Guard Option
Aftermarket bumpers, brush guards, or fog-light housings can change the job. Send a photo of the front if the bumper is not stock.

A baseplate existing for a vehicle does not mean that vehicle is approved to flat tow. Check the recreational-towing section of the owner’s manual before you buy. Call 877-736-2267 and we will walk it with you.

Inside kit BX88464

Finish the hookup. Safe & Easy.

The brake and the height fix stay on this page so the price stays the package price. Extra finish items sit in the featured boxes below the description.

ADD A BRAKE — OPTIONS

The toad stops itself

Without a brake, the motorhome stops and the tow bar has to stop the car — thousands of pounds, times momentum, shoved through two steel arms. With a brake, the toad stops itself. The bar is not squeezed. Required by law in most states and provinces. Add the Patriot under Add a Brake in Options on this page. That is the package price. Do not buy the brake as a separate item.

KEEP THE BAR LEVEL

Within 3" of level. 0" is the goal.

Tab height is fixed on this Standard plate. If the coach receiver sits more than 3" high or low, add the 8" rise/drop in Options when it is offered on this page. Call 877-736-2267 if you want the height walked before you order.

Already own a Roadmaster or Demco bar? You do not need this complete package — you need the plate plus an adapter. Skip adapters if the bar is Blue Ox.

Questions we get on this package

Can a 2006–2010 Hummer H3 be flat towed?

Blue Ox built a plate for the 2006–2010 Hummer H3 (Works with Factory Brush Guard Option). That is not the same as Hummer approving four-down towing. Read the recreational towing section of the owner’s manual, or call us with the exact year and transmission. We will tell you honestly if something else is a better fit.

Why Avail instead of Alpha?

Alpha is the classic 8,500 lb, 2" bar. Avail is the premium 10,000 lb bar, and Avail is the one that also comes in 2.5" at no extra cost. Pick Avail when you want the extra capacity, the current Avail arms, or a 2.5" hitch on the coach. Same plate either way. Ask us for the Alpha package on BX4104 if the toad is light and the hitch is 2".

Do I need a brake?

In most U.S. states and Canadian provinces, yes. More important: without one, the coach brakes and the bar has to stop the car. With one, the toad stops itself. The bar is not squeezed by thousands of pounds multiplied by momentum. Add it under Add a Brake in Options. That keeps the package price. Buying the Patriot as its own product is the MAP price.

The coach hitch is 2.5 inch. Will Avail work?

Yes. Avail is the Blue Ox bar that comes in 2.5" at the same price as 2". Pick the 2.5" receiver in Options on this page when it is offered. That is cleaner than a reducer sleeve on a 2" shank.

Can I install this myself?

Many customers do. The plate is the longest step. The bar and kit are hookup, not fabrication. We are on the phone if you get stuck. If you would rather a shop does the plate, we can help you talk to them. Blue Ox also has a dealer-install network.

How does it ship?

Three factory-sealed cartons. Add a brake in Options and it is four. Free shipping over $100. Canada ships too.

Free shipping over $100 from RV Camp Champ. Safe & Easy, from ordering to installation.
