affect lol
i took my 79 to my buddies house till i find a new place and it was the first time towing with the lift and 37s i def need some gears in it ... it still pulls pretty good but i sure did burn some fuel .. now it wasn't quite that bad lol it leveled up to about 7.5 plus my computer still is set for a 33" tall tire so add another mpg roughly also to add there was 3 transmissions in the bed and the damn trailer is heavy from jump lol
