Hello Paul NC ,
Ive talked to a few people about the timbrin ,they are like big rubber bumpers
that take the load under load.Eaton Detroit Spring can build you new rear leaves by application ,you give them your vehical info and number of leaves and that you want to increase carrying capacity .The double bellow air
bags are really good ,but the leaf spring upgrades are the best bet.you do
not have to have them be too rigid ,but increase the capacity .Ive done a set on a E150 1994 for a customer and used the Eaton springs ,worked out well .not a tow vehical ,just a work truck .The bags do allow you to increase
capacity and retain the ride not towing .That said ,the correct setup of your equalizer should get your TV and trailer level without any bags or heavier springs ,so look into the hitch adjustments ,it should not have any rear squat
if all is correct when hitched up .
