Thanks. It's a vary rare 1964 Dunphy X-55. I tow the X-55 with an X5.

500 mile tow

I just finished towing my new (to us) 16.5' jet boat 500 miles from western Philadelphia to central Ohio. The X5 towed wonderfully. You could feel that the boat was there, but it was stable, and at no point did I feel like the boat was controlling the tow vehicle. I had plenty of passing power, and was able to sustain 75+ through the hills in western PA and WV.

Mileage, however was not such a rosy story. I averaged a bit over 21 on the way out (unladen), and a whopping 14 on the way back.

One interesting thing--prior to this trip, my front brake servcie indicator said front brakes wouldn't be needed for another 23k miles (the X5 turned 35K on the trip). Now the iDrive says 1300. On the upside, that would fall in the BMW-paid maintenance window, but I'm concerned as to why the sudden and drastic change. Looking through the wheel, the pads don't look worn to the level where they'd need replacement in 1800 miles.

What does your X5 look like when you attach a 500-to-600 lb tongue weight?

640 and the total load was more than 10% of that number. The air suspension keep me level. The 35d had no problem pulling, however it was too much weight hooked to the back of the truck,

For the record, If I knew this load was as heavy as it was, I never would have hooked up. I was given a dry weight for the boat (from the manufacture) and the weight of the trailer from the trailer manufacture. I estimated another 500-750 for the limited gear (small danforth, 3 fenders, bimini top, cockpit cover, and splash of fuel (less than an 1/8 of a tank.

Needless to say, Sea Ray probably fudged the numbers on the boat's weight. Fortunately I was able to make the short distance w/o any issues. However, I did get it weighted, b/c it did not feel like the 6700-7200 that was estimated.

Wait, so the total weight towed was more than 7000 lbs? What was the weight?

Its the stopping that counts, the 35D will definitely pull more than the rated 6000 lbs. Can you stop it though, have you done an emergency stop too see just how long the increased braking distance is?

What is the weight of the boat and the weight of the trailer?

I have a 25ft Cobalt (model 252 with a 454CI/7.4l V-P), dry weight 4530lbs and a dual axle Venture Aluminum trailer, weight 1,050 for a total of about 5,600lbs dry. With fuel probably about 6,000lbs. Tongue weight: 310lbs, or 5%

Your Sea Ray looks to be a closed bow series, about 26ft or so and a dual axle (galvanized?) trailer ... I suppose it could approach 7,000lbs ... But you shouldn't have tongue weight around 700lbs. Something is wrong. Boat is probably too far forward ...

Blue Dragon-
I didn't do an emergency test stop. I was on a two lane road for most of the trip and the interstate for last few miles. The speed limit on the two lane road ranged from 35-50 mph and I did not go above the limit. I stayed in the right lane on the interstate and had no issues getting on or off the hwy.
I was keeping several hundred feet between any traffic in front and had plenty of room to stop for any yellow lights. When I needed to use the breaks they felt OK, but not confidence inspiring.
From a pulling standpoint, there were no issues. However when I went over bumps or uneven pavement, it felt like the trailer was pulling/ pushing the X5. Which makes me wonder if it could damage the unibody?


PAX5-
Sea Ray states the Pachanga 27 is 5,200 dry and Load Right states the trailer should be around 1,200 (give or take 100 pounds). It's a galvanized roller trailer.
The tongue weight is in the range of 7% of the total load, so I assume the weight is properly proportioned.
My assumption was 5,200 boat + 750 for contents (almost no gas) + 1,200 trailer and figured I would be around 7,000-7,300. Had I know I was going to be over the 7,700 (European rating). I never would have hooked up.


Prior to learning the actual weight of the boat I planed to use the X5 to launch it at the local ramp which is 1.7 miles away from where it's stored. Now I'm trying to figure out how to get it to the boat ramp- other wise, I may have to keep it in a slip. .

Have you seen considerable improvement in stopping (while towing) since upgrading front brake rotors/pads to X5M?

P.S. Why upgraded just the fronts?

I've been wondering about this for a while:
The X5 has some of largest disk rotors out of SUVs. A Suburban or a Tahoe has quite small rotors compared to X5, too small for vehicle of that size.

How is that Tahoe (a similar wheel base length) is allowed to (and considered to be able to ) tow more than X5? I can't imagine those puny brakes being able to hold the heavy Tahoe and the towed load.

Suburban may be a different topic, as it has longer wheel base - usually better for towing.

Yes, the most noticeable difference was towing, around town with no tow, there is not much difference except for pedal feel.

The X5 M rear rotors have a different hub size, they cannot be directly bolted on.

Isn't it not a good idea to have mismatched front/rear brakes? Bigger front brakes will grab more percentage wise. I thought manufacturers calibrate brake size to match vehicle weight on each axle..
Unless cars these days adjust automatically to load..

As far as I could tell, the rear caliper on the X5M is still a single piston caliper with very similar diameter to the non X5. The X5 has the ability to move the braking force around, it can brake one wheel if necessary.

Just a few pics from my recent move to Houston from Minneapolis. Trailer weighed 7420 pounds as verified by a truck stop scale. That is just the weight of the trailer, not the vehicle plus trailer. I drove over the scale until only the trailer wheels were on the scale. Just under the Invisihitch total capacity. The trip was nice and uneventful. Could feel that you were towing a heavy load, but the X handled it well. There was never any feeling that the engine was straining or struggling. Averaged 15 mpg, and even got 20 on level roads at an average of 65mph. Definitely helps to shift manually and leave it in 6th once you reach cruising speed.

I have the rear air suspension, so the X was level all the time. No difference from if it was unladen.

Love my X. This one is a keeper for sure.
