Tow Bar Height Difference coach to tow car
When using a tow bar and towing a car 4 wheels down, Blue Ox
recommends a max difference of 4" from coach receiver to attachment
point on the toad. None of our Birds are even close to this with
95% of tow cars.

I "had" a 10 inch difference, using a aluminum Blue Ox Alladin tow
bar rated at 5,000 pounds, towing a Geo Prizm approx weight 2500
lbs, total towing miles about 10,000 in 3 years.

Last week on a trip, I hit a series of large bumps and dips that
were not readily visible, so I did not slow down in time. The Blue
Ox sheared at the exact entry point into the receiver on the coach,
so the car and the rest of the tow bar broke loose attached only by
the safety cables. "Luckily", this was in a safe area to pull over
rather than the 1 lane interstate construction I had just left,
where I would have backed up traffic for miles, and likely had
greater damage.

To complete the trip I bought a Blue Ox Aventa II steel tow bar
reated at 10,000 lbs. I will be sending the aluminum broken bar to
Blue Ox, and they will repair it at no charge other than my shipping
cost. That still leaves me 2 bars, and a damaged tow car.

I will be buying a 4" drop hitch, and am changing to a taller tow
car (was doing so anyway), and plan to keep and run the 10,000 pound
bar and sell the 5,000 pound bar.

If you are towing 4 down, check your height difference, and consider
a drop receiver hitch.

Tow Bar Height Difference coach to tow car
Good info Dan. I had my Excalibar modified (with Demco permission) to
adjust for height difference on my SOB to 4 inches. Now that I have the
Bird I think there is more like 6 inch difference. I always thought the
manufacturers wanted the heigh difference minimized to prevent the
possibility of the toad diving under the RV in the event of severe braking
with resultant RV nose dive & rear up. Wasn't aware the height diff could
cause breaking and failure of a tow bar. I do agree you are doing the right
thing with a 10000lb bar. In the case of tow bars I believe 'more is
better' IMHO.

One of these links (with a cut and paste) might work for pics.

The road set up a fairly severe front/rear
bouncing of the coach before I could slow down (Spartan Chassis 2
axle). I was thinking to myself I might lose a air bag as I was
slowing, but did not think tow bar. This was on a back street in
Lawton OK versus hi-way or interstate, speed probably 30 MPH. This
is my second motorhome (83 FC35 first one), and the most severe
bounce I have experienced.

Even though perhaps a "freak" occurence, I now advise a drop
receiver hitch to reduce height differences. Blue Ox and Towing
World have a 10,000lb rated drop receiver in various heights. The
next problem may be entry and exit on steep ramps with the drop
receiver dragging. I am debating a 2" drop, or a 4" drop. Will
likely go 4" drop with a drag wheel.

Tow Bar Height Difference coach to tow car
Hi Dan,

Sorry to hear of your tow problems. I have a Blue Ox aluminum tow
bar and FYI, last fall at the RITV, the Blue Ox folks came by and
swapped the aluminum tube to a steel one. They must be aware there
were problems. Now, whether or not a level tow bar would have a
problem, we don't know. Mine, on the LXi, with a Jeep is almost
dead level. They seem to be good people to deal with but may give
you a hard time on covering any damage because of the height
difference disclaimer. Hope they fix you up.

No coverage offered by Blue OX for damage to tow car nor BMC
(minimal to BMC), but they are rebuilding and R & Ring the tow bar.
RV insurance covering the BMC. I think I'll eat the tow car damage
myself.
