I purchased a Wilderness 2875BH last year. The first year this model was manufactured. The unit has two opposing slides, and a center island. Overall quality has been more than acceptable, I had the unit in for one service call when the air conditioner drains plugged with pin needles, at which time I had the dealer reseal all external openings and windows. The microwave died but that is not the fault of Heartland.
The bad the dealer sold me a Eazi Lift weight distribution hitch with a static sway bar and a generic brake controller. The unit towed horrible and was not an enjoyable towing experience. This spring I upgraded to a Equalizer four point hitch with 1200 lbs bars instead of the 1000 on the Eazi Lift I also purchased a Prodigy brake controller. Night and day difference I towed from Maine to Niagra Falls NY and back and the drive was 100 times better.
I tow with a 2009 Chevy Silverado with towing package 3.75 rear end, transmission cooler, and 5.3. The truck is able to tow 9600lbs and payload is 1600 lbs. Advertised tongue weight is 660 lbs I am little over that at 725lbs. Advertised trailer weight is 7800 lbs and that is about were I am at. Gas mileage varied from low of 7 to high of 9mpg of course the trees were blowing in the direction I was headed that day. The only issue with this truck is the lack of power. I have been looking at 3/4 tons I feel the 6.0 liter would be better. My family is only going to get heavier and I would like a cap on the truck to stow bikes and carry my dog.
Overall I have been very happy. I hope this may help those that are looking On edit yes I weighed with spring bars attached I also found half a tank of fresh water made a world of difference, since tank is in front.
