add new shocks to your budget boost. if you have 250k on it then im sure they could be replaced. another option is bushwacker cut-out flares. pretty much trims the fenders up and out of the way and adds a nice flare to cover your bigger tires. these with the BB lift would get you a 31" tire i bet. the flares will be nice if you play in the mud, as in no clumps of mud on the roof to clean. as for tires, there are a lot of street friendly mud tires out now. so give them a shot, toyo, goodyear, pro comp, bfg, mickey thompson. look for those 4 for 3 deals.
oh and an upgraded steering damper wont hurt either. look for a used gastank skid, and t/case skid.
good luck
