Trailer Width - Pros and Cons

For towing safely, I always make sure I can see straight down the trailer sides. So that means mirror extensions for me. The slip over ones are great if you can find them for your model. They are usually expensive IMHO.
For my recent TT purchase, I bought the only extension mirrors I could find quickly for my Explorer after I measured and found the outer edge of my mirrors was the same width as the new trailer would be.They did not work well because they were designed to strap on fully rectangular mirrors and my mirror bottoms have an angle to them. I could use the driver's side but the right side would not adjust right. And the vibration was bad. Got the new trailer home. I bought those mirrors from Walmart's auto section. Thought I would take a heat gun to the bracket and form it to my mirror housing shape. THEN I found these suction cup mount ones in walmart's RV aisle, sold on eBay from the U.K. tested at over 100mph to hold. Returned the original extensions. There is a twist knob to increase the holding auction. Now I can use my power mirror function to adjust the new extensions.

The stock mirrors on my F-150 allowed me to see behind the TT, just not too well.

The extended mirrors allow my to see closer behind me. However, nothing short of a rear mounted camera will fill in the blind spot directly behind the TT.

It is still my opinion that you choose a TT based on floor plan. Other problems can be resolved,

With something like a Highlander trailer wind resistance is a significant issue at highway speeds. A narrower and more aerodynamic trailer would be an advantage.

I am not one of those people who says "you need a bigger truck, you need a fancier hitch, you need X, you need Y."

But you DO need towing mirrors. Don't be penny wise and pound foolish. When you are trying to change lanes in dense and fast urban traffic (try 50 mph bumper to bumper LA freeways), you have to be able to gauge your opening, especially when moving right.

I use clip on mirrors. They are good enough. After-market extension mirrors are better than clip ons -- less vibration.

There are lots of decent mirror extensions. If you want to see how much of a difference a foot can make in a trailer, google a Jayco 174 AND an Aspen Trail 1700BH. Irrespective of ones opinion of the companies, look at space differences. They are the same floorplan but the Aspen Trail is one foot wider. You go from like 29 inch bunks to a 41 inch bottom bunk. You go from a small two person dinette to a decent sized four person. You get quite a bit more storage at one end of the bed also. That difference is well worth the slight hassle of mirror extensions.

my Highlander with towing package towed a 3500 lb. TT just fine. contrary to some here, you don't need a F550 to do it.
and my my strap on mirrors were closer to $40 and I first bought one, put it on took it for a drive to see if it vibrated too much. it was fine so I went back and bought the second one.

I guess you do not remember my 5.3 v8 trailblazer with same guts as any half ton could not handle the full height frontal narrow width 3400 empty 5000 loader hybrid.

whoa, I am talking about a 3500 lb. TT, not a 5,000 lb one, but my highlander is rated to tow 5,000.

If you dont want mirror extensions, then be prepared either for tickets, or no trailer. You absolutely MUST have a clear view behind you. It is the law afterall. So your choice is pretty clear.

Show us this law?

I've towed 50,000 miles transporting RVs to dealers from factories and can't see behind me with my tow mirrors, and no one has ever ticketed me.

Out of curiosity I Googled this topic and as usual came up with an endless list of references, including this one that does indicate that in many Canadian provinces and US states mirrors that allow a clear view of the highway ~ 200' to the rear is required. I know for a fact that the stock electric mirrors on my Silverado sure don't extend out far enough to see that far back along the highway when I'm towing so I'm quite happy to be using a set of CIPA slip on mirrors that do. :)

Same old tired response :S ... no one has suggested the OP needs an F550 to tow his hybrid, rather a few have just pointed out how limited is Highlander is for towing. Nothing more, nothing less. :R

The Highlander is also a relatively narrow vehicle so towing mirrors IMO are highly recommended regardless of the width of the trailer the OP is towing.
