I'm the person with Bigfoot slide out issues. On our 2008 30C1002 the slide end support roller wore into the floor structure. After several hours of panic as we were supposed to leave for Mexico in two weeks with advice and construction pictures from Grant at the new factory I was able to resolve the problem for about $30. I jacked up each side, filled the groove with some thickened epoxy and then slipped a sheet of 16 ga sheet metal under the roller as a wear plate. With some screws and butyl caulk the problem was solved. That has been three years now.
Bought an older 2500 9.6 a month ago and am modifying it to go to South America right now. We also prefer the center bath of the 9.4 and 30C, but this is what was available and didn't care for the non-slide Lance units we saw. Peru is not the place to be taking a slide as parts are a long distance and time away and our 30C is irreplaceable. JM2C.
Having poked one hole in the roof on our original 9.4 which was easily repaired with fiberglass and then having a mule deer take off both jacks on one side again easily repaired by the local body shop I really like the clam shell construction.
