My 2004 has electric slides & jacks, the 2005 and up are hydraulic. Overall the unit your looking at worked well for us full time, but some things to check. The rigs came with 7,000lb axles standard and 8,000 were an option. The g rated tires were almost overloaded at the 7,000 loads and the H tire was an option, better in my opinion.If your trailer is the 16,000 gvwr the trailer is heavy, depending on options and does not leave much carrying capacity if your full timing. My trailer was as heavy as 17,200 with a 4,200 lb pin. We pared that down over time but the trailers do tend to have a heavy pin overall. The thick walls help with sound proofing and temperature control. Many units were equipped with dual pane glass, some had the seals fail, the glass didn't break, just fogged up.The gel-coat can easily be polished and the graphics are all paint except for the decal on the nose. A good rub out and polish can bring most any dull rig back to life. The web site for the owners of these units is
here and asking any other questions there might be helpful to you. The prices seem to level off at the 25-30 range for the year you are looking at, again depending on condition and options. Hope this helps
