Because the whole Hoffman clan is making money. Pay attention!! Most of them are driving new or newer trucks with lift kits on them and they are now pulling travel trailers instead of living in tents, etc... They are being payed well for their antics on the show....
I suppose. Even old brokeback Harness had some doctors give him a gratis surgery so I guess it's working out for them.
I wouldn't want to be on TV looking like a fool though, no matter what kind of truck I get out of the deal.
