I've had my Bigfoot
for about 2 years an have towed it with an 07 Toyota Tacoma 4x4 with tow package. It is a very good combination of trailer and tow vehicle. I use Mckesh mirrors but I don't think you will find them new anymore. Someone else makes a similar mirror to Mckesh but I don't remember who.
Gas mileage----- that's another story ! Wind has a huge effect on fuel consumption. Best I ever got was about 13 1/2 on level ground and 7 1/2 when it was very windy and mountainous . In the 2 years I've had the Bigfoot
I've towed it about 15000 miles and I have the gas receipts to prove it ! Also had lots of fun.
