7000 miles on the stock trailer

Post by mastreb »

Hey all,

So we're _nearly_ done with what has turned into a six week long odyssey around the U.S. with our MacGregor. We left home port San Diego to go to the MUCK-about sail, where we got in all of about 45 minutes of actual sailing for our 7,000 miles of towing :D :D :D

Firstly, we had a great time meeting people and putting names to faces. Everyone we met was just fantastic, and despite the fact that we didn't get much sailing done because of the weather we had a great time.

We also had a fantastic time on the trip there and back again, seeing old friends and new, and doing all kinds of things we never would have done had we not been driving past, like going to Niagara Falls, seeing a full-scale re-enactment of the Battle of Gettysburg on the 150th anniversary, watching fireworks from the boat in Hudson, visiting all the stuff in Manhattan, going to all the monuments and museums in D.C., stopping by Roswell NM and Carlsbad caverns--the list is too long to recount here. Suffice it to say that while the MUCK was our "goal", it was the journey that we really loved. A metaphor for life I'd say.

Anyway, I thought I'd post my thoughts about the quality and reliability of the stock trailer. Firstly, we have the "upgraded" factory trailer, which came with stainless steel brakes.

Tires:

It came from the factory improperly inflated to 32 pounds, and because I misunderstood the sidewall, I left it that way and trailered it over 3000 miles half-inflated. This resulted in the loss of all of the side-tread on the stock Carlisle bias-ply 225/75D15 tires.

Despite that loss, I trailered it another 3000 miles until in Albuquerque it became clear that I was pushing it way beyond reasonable. We were now missing chunks of tire and had exposed threads. The Discount tire guy said they were the worst tires he'd ever seen come in that were still inflated. No need for a chorus of how irresponsible/lucky I was with the tires, I already know :P

Replaced them with Radials, which are FAR smoother.

Despite the severe tire damage that was all my fault, we never had any trailer problems and were able to sustain 75MPH on the freeway reliably. 75MPH was our standard speed. With the radials it was even smoother.

I strongly recommend radials. They're way smoother, quieter, and they wear evenly (not in chunks). Also they're only about $10 more than bias ply. They'll likely last the life of the trailer.

Drawbar:

It's iron, it rusts. The rust converter I put on has worked well, except in the areas where I didn't spray it. It wasn't effective in the non-treated areas at all for some reason. In any case, the stock jack rusted to the point of uselessness, and I replaced it at a West Marine with a Fulton bolt-on for $150 that works way better. Otherwise, the trailer is in good shape, with the aluminum showing no problems after three years in Salt and with a neglectful owner. A fully aluminum trailer should have no issues.

Hubs:

I way over-greased when we started out. I still have grease squeezing out and getting all over everything. But a greasy hub is a happy hub, and we've had zero issues with hubs overheating the entire trip. Hubs have simply been about 50 degrees above ambient the entire time, and never too hot to hold a finger on, which is a good test for overheating if you don't mind burning yourself.

Lights:

Corroded through. When we lost a lightbulb, I wound up completely rewiring the trailer with a $40 set of "over 80"" submersible lights from O'Reilly auto-parts and a $20 7-way plug. It was easy, taking just three hours to replace every bit of wiring on the trailer. My plan is to just rewire the trailer whenever it's a problem, as getting three years out of a $40 investment is worth it IMHO.

Licence plate:

Lost at the Liberty Park launch ramp in New Jersey. Replaced with a printout of our license plate number stuck to the back of the boat with a FEDEX address envelope.

Surge brakes:

A bit "stuck" in that they go hard on and then release without a very smooth braking action. WD-40 on the piston seems to have fixed this. Otherwise working great, and I credit them with avoiding a jackknife in a hard-braking situation in D.C.

Summary:

We still haven't gotten home, but with the boat properly strapped to the trailer, we've had zero issues with the single-axle stock aluminum trailer that weren't ultimately my fault. Even with a lack of maintenance on my part, it has done just fine. The maneuverability of the single axle has been critical in getting around these east-coast cities: We dragged it all around downtown Philadelphia and parked it on the street there to visit the Liberty Bell, all with no issues. I won't be going to a dual axle because I value the extreme maneuverability of the single axle and now know it to be sufficient for the boat.

Roger certainly engineers to the limits, but not beyond them.

That trailer light set from O'reillys; I'm thinking I have the same set. Supposedly water proof? Right. Not. Wait until you try and change a bulb - the bulb mounting sockets are unbelievably badly done if its the same set. I don't expect the set to last more than 2 years.

I hope people are aware that TRAILER TIRES are not the same thing as CAR TIRES. People often install car tires on a trailer to save a few bucks. Trailer tires have stiffer side walls than car tires and cost more. A car tire is designed to roll under a little on corners, trailer tires are to do the opposite.

I'm ok with the single axle stock trailer and have never felt an urgent need to install a 2nd axle.

Glad you have the time and and resources for such a trip. I'm envious.

Nice feedback on the trailer. Gives me some confidence that mine will last a while.

On the lights, I have already have a tail light and side marker stop working (I tow only about 120 miles per year). The side marker was due to a bad electrical interface to the bulb. The tail light had a bad bulb. This year I replaced all the trailer lights with submersible LED and we will see how well it holds up.

I think I remember you saying earlier that you towed with a truck, but did you learn anything about loading the boat to reduce side sway?

fwiw... I keep reading accounts on RV.net about how Carlisle tires fail the mission...

Glad you had a good trip!... any pics??!

We towed with a Mercedes-Benz GL350, which is a 6-cyl turbodiesel SUV. It has a 7500# tow rating. It detects the presence of a trailer (current through the tow plug) and activates "Trailer Stability Assist" which individually brakes the truck's wheels to stop any instability (I have no idea how it detects instability). It apparently works, because we had zero sway the entire time. Even going over a big bump the trailer just damped immediately and was back in line behind the truck. With the radials on the trailer, it's easy to forget that you're even towing anything.

Around 85mph it did start to feel wobbly in the back, so I kept it below 80mph the entire time. We did the majority of the trip at 75mph where it was rock solid.

My basic advice on loading would be to get the tongue weight and load the boat to put the tongue maximum for your vehicle on it. The heavier your tongue, the less sway you'll have. Our tonge load was about 400# out of a vehicle maximum of 600#

I'm blaming myself for the failure of the Carlisle bias plys I had on, but the new radials are also carlisle. We'll have to see how they last. I'll post a bunch of pics when I get home.

The technology used in your vehicle's stability comes from MEMS (Micro-electromechanical systems). These are accelerometers and gyros on a chip produced by Analog Devices, Texas Instruments and a few other chip companies. They also control the activation of air bags. Amazing stuff!

It wasn't much more than a full-sized tow-beast. I think we paid $62K?

You guy's are forgetting the great Canadian markup! (even bigger sigh)
Oh yeah I forgot - Free Trade - The great leveler. :(
I think an off lease Ford 150 flex is going to happen next year.

after buying a new set of carsiles in north carolina i had 4 tires explode on the interstate in 500 miles @65 mph ..i cant imagine anything more frightening than changing tires on the side of the interstate with the wife and kids in the truck ...who ever was responsible for the quality control at carslile should be in prison ,,they are playing with peoples lives .....they never questioned anything about the tires ,they sent me new ones which would blow out ,,,thousands of dollars in damage to BOTH sides of my camper .....spent a fortune having axle alignment ,brakes hubs all checked ,it wasnt until i googled carslile tires that i saw how deadly they were ,,,,funny thing after i put new maxxis tires on i never had another problem ........

What OTHER vehicles have "Trailer Stability Assist" 8)

The M class has apparently had it since 2005.
