If you lived in Canada, a lot of the stuff that you need to get to the RTL-E for is available at lower levels. So that's always an option. :grin:
I think the whole forum agrees with you about the rear window, even folks like me who have an RTL-E. I think there should be a manual window option at the very least. The RTL-E has an electric rear window, which is nice and all. But a manual window would've been fine in my book. To have a pickup truck without such a window through most of the trim levels is a huge mistake.
Most trucks have part-time four-wheel-drive. The Ridgeline doesn't offer that. Your choices are front-wheel-drive (FWD) and all-wheel-drive (AWD). With AWD, traction to all four wheels is always available, if needed. The Ridgeline uses a pretty good set of electronics to control wheel slip and ultimately maximize traction. It's yet to have an objective, comprehensive off-road test by an independent authority. We're going to see those soon though. But bottom line, if off-roading is your thing, the Ridgeline is most likely not the best choice for you.
And yes, FWD-only Ridgelines are rated at 3500 pounds for towing. It's 5000 pounds for AWD.
Last I checked, the Tacoma didn't have heated mirrors at all. You might want to check out the Canyon/Colorado, which have the tow rating of 7000 pounds. The Tacoma is a little less than that as I recall, around 6500 from memory. The Tacoma definitely comes in longer bed configurations both with and without the double cab.
You should look at the Ridgeline bed carefully; it's a lot more functional than the Tacoma short bed. Yes, it's very shallow, which bothered me a lot before I bought it. But when it comes to real-world loading, I've been getting a lot more stuff in the back of the Ridgeline than I ever did in my Tacomas. (That's especially true if you include the trunk.) Having an almost fully flat floor that's 5 feet wide is a bigger deal than I realized.
