Welcome the forum from another Cyclone owner. Great product and great company to work with. I've had my share of problems at the beginning but not with Heartland. More than anything, I recommend two things. 1. When shopping, take another experienced RVer with you or a least one time before the final decision on a purchase. 2. During the PDI, again take another RVer with you.
That may be a little extreme to some, but that's my first buying experience speaking.
Ford F350 is good, but be careful to get the right model. Be sure the 2013 model has the 3.73 axle ratio. Any other model will be to light for the 4000 or 4100. The 3500s are a little more straight forward and will be fine. Personally, I'm Ram Truck fan. The 2013 Ram 3500 is going to be tough to beat, that is if they every get it the showroom floor.
Arctic Package? Seems like I read somewhere you have to order that by special request before the build. I could be wrong.
If haven't done so, join the Club and get some additional benefits.
