Congrats on the new Surveyor. This looks like a longer version of our Wildwood. Also roughly the same configuration and weight. While the 3/4 ton Duramax is very capable, I'd recommend the WDH and anti-sway. I've pulled our TT without the WDH for short distances and can say I would not pull our TT without the WDH anti-sway set up on any trip loaded. The difference is quite noticeable. I feel much more comfortable and stable (rock solid) using the WDH. We do a fair amount of two lane road, scenic-by-way driving and having the extra measure of control is great!
For our money, well worth the investment.
