Depends of course on size, ground clearance and access (underneath and in walls/floors), how dirty it is underneath (insects, animal leavings, junk, sewage or mud on ground, etc), how much it is insulated, whether the piping underneath is embedded in spray-in insulation or not, if having new insulation put in as part of the job, whether replacing just water pipes or water and drain and if going to ground line or to meter and street connection or what.

Generally speaking and assuming single-story (at least as far as water goes), for just water line replacemetn and keeping the same faucets and fixtures, probably $1000 minimum unless VERY simple and wide-open (maybe as low as $500-1000 if on of those designed so all water uses are in one very tight area, but not likely with your square footage), and maybe up to $1500-2000 excluding excessively difficult access cases. Drain lines probably another $1000 minimum - cheapest if hung off the bottom of the trailer, up to about double cost if embedded in insulation that has to be removed and then replaced.

Heat taping costs more - because have to remove and then put on the new piping.

Also - copper piping rather than flex within the confines of the unit (as opposed to from the unit into and under the ground) may add about 25% to the cost.

Plus maybe some trailer repair or handyman cost to repair openings to access the piping if needed - though in most trailers not much is run in the walls - mostly it is under the floor, so that is usually pretty much avoidable - but be sure to talk to the bidders about exactly how much opening up they will have to do, because some go hammer and sawzall happy while some will really make an effort to avoid damage to visible surfaces.

So - bottom line, assuming you are not in an extremely high-cost area, I would expect bids (get at least 3 responsive bids) from Plumbers or Mobile Home specialty repair/maintenance places to run from around the numbers I gave above to maybe 50-100% more, because a lot of plumbers will bid trailer home jobs but hate them so bid way up on them.
