Thanks Frank!
My daily driver is a Gen 1 Honda Insight and it bears the brunt of most day to day driving tasks.
The truck only gets pulled out a few times a month to haul mulch, manure, straw, and any larger or messy items that I can't or won't jam into the Insight! LOL Aside from those tasks the truck is largely used for highway loads between my home and some property I own in MO and is generally hauling or towing and doing things I simply cannot with the car.
So that is why the question on the tonneau vs the cap/shell/topper question. I seem to see conflicting info on the effects of the topper so I thought I would ask to see if there is any consensus building on the effect of the topper. The tests done by a topper manufacturer and the video is poor and really can't be used in any meaningful way.
Thanks again for you feedback.
