Simply, I think yes
I studied up on several brands and decided to go with Roadmaster based on reviews, design and price. Point being price was part of the equation but by no means the prime motivation. I think you are pricing it without the brackets because if memory serves it was in the 300-400 range (shipped).
I put it on my F-53 chassis, 2003, about 6 months ago. Installation was easy but instructions are very confusing the illustrations that accompany the instructions show it mounted opposite of what the instructions tell you. First impressions driving were, WOW.....wheel centered much better when turning, stability on level flat road was much better, cross wind was improved but by no means eliminated, overall scale of 1-10 I would rate it a solid 8. Plus I have the added peace of mind that I have it there to assist in the event of a front tire failure. It appears to be very well constructed and simple in design. Would I recommend it to a fellow RV'er, yes absolutely.
Hope it helps, I like you see the prices of some of those other devices and say at more than double to three times the price are they that much better, my conclusion is no. Sort of reminds me of a problem I had recently, mice in a storage room, I put out 2 old fashioned traps with peanut butter, the exterminator brought by a new electronic device which he says is the latest greatest, all stainless steel and plexiglass, I'm sure it was a couple of hundred dollar trap. Result go back two days later......mouse in each of my traps, his empty!
