Harker Topper on 4th Gen

I just got a Harker EXO on my 4th Gen and we love it. Definitely going to have to upgrade the suspension as the truck sits about 3 inches lower. Total weight of camper is 350 pounds plus everything else that is loaded my truck. The truck handles the weight incredibly well besides being lower. Gas milage since installed (500 miles ago) dropped about 0.1 but those are high way miles. I had a much bigger drop in mpg after adding KO3s.

 

What your options for springs to support the added weight?

 

All my research has produced nothing ... no real options at them moment....

 

Can’t remember where but there’s a couple people using Tundra springs. They said they are pretty stiff, probably be about right with that set up?

 

I will follow up on this lead... possible option
