Does anyone have any recommendations for towing mirrors?

I will be towing a 29' Travel trailer in the next few months and I am having a difficult time finding decent towing mirrors. They almost seem non-existant which makes me wonder if the H2 is wide enough that I won't even need them? Any Comments? Thoughts? Recommendations?

If I do need mirrors, I am hoping to find something like the **** ones that slide over the existing mirror, instead of the "Strap On" type.

Thanks

I was towing my 30' to have some warranty work done, and definately could have used a little more mirror.

i only use mine on long trips, but they're the strap on kind and end up drooping like the ears on a bassett hound after about 100 miles. don't know of any that slip over for the H2 mirrors.

 

I could use them also. My enclosed car trailer needs just a bit more mirror too.
