I have been using a Jeep Cherokee as my toad. It has worked great. I have a 94 Newmar Mountainaire 460 ford, 37 foot, one slide. I believe the trailblazer is heavier. I don't know how bad an effect this will have. Can anyone advise or direct me to a site that would have this info. My main concern would be going up Lavita Pass from the east. Anyway, think it will pull me up that hill?
