I pull my X20E with my 2012 DLCB no problem. Note: I do have the tow package. I even filled the Fresh water Tanks and pulled it all over Ontario this summer. I don't plan to do that all the time, but I am much more confident knowing the truck can handle it and without that weight I'm even more comfy.
When Towing I would just lock out the Overdrive (ODO) and leave it in 4th gear and set the cruise for the flat runs and minor hill climbs. Bump down to 3rd if I needed to pick up some speed on the uphill climbs but only if I had a big rig bearing down on me. Otherwise no problem at all.
For mirrors, I bought some PROEFX off a group buy at TacomaWorld.com
Talk to Rob Aka Macha1Man001. He can hook you up. I had one fail because I clipped another mirror/trunk in a parking lot and he replaced it for me no questions asked. I go by CDNTACO over there.

The Mirrors on my truck fold out and then I can see around the trailer no problem.
Aside from that, Get a good WD Hitch and Brake Controller. It makes a world of difference and don't be in a rush to get anywhere when towing.
Deployed View (Not my truck) but shows how they fold out.
