I just ordered a VRV 718 from VRV Inc. I chose the VRV for the same reasons you are, and I will be towing with a Tacoma as well.
I went with VRV Inc. rather than Livin Lite for 3 reasons
- A reasonable sized blackwater tank
- Lower price than Livin Lite
- ATC makes the trailers and ATC is very reputable (with great warranty)
One thing to think of is not only weight but size. I originally planned on a 818 (8 1/2 wide by 19 feet long), but Tom (VRV Inc.) recommended 615 (6 x 15) for the Tacoma, which is much smaller. This recommendation was due to wind resistance from towing at speed. The Tacoma pushes a lot less wind than a full size. I settled on a 718.
Best of luck on your search. I will receive the TH in about 8 weeks. Let me know if you want any feedback once I receive it.
