Hmm, if you need low range, then a regular truck will suit your needs better. 4WD-i (on the HiHy and RXh) can't do deep muddy trails. Light offroad is about as good as it can handle.

Now the FEH's 4WD system is mechanical (i.e. traditional) so it might suit you better. In Canada, they've dropped the price and increased the hybrid warranty.

The other option is wait for the Tundra Hybrid but it might be costly.
