Welcome! We bought ours (though not a Conquest) new over a year ago and have had no leak issues or real issues with overall construction but YES, if you buy new you will want to go over your new unit really well before using it and getting stuff moved in. What I've found on ours as soon as we brought it home (and was expecting to do this anyways as preventive measures from previously owing a used TT) was to re-Dicor any iff looking seals on the roof, touch up any silicone on the exterior siding/lights etc, though ours was good, checked the AC roof mount (done from inside) and check and snug up all the drain/water fitings for the sinks, tub, toilet. We found a loose P-trap on ours and a few barely finger tight water fittings on the sink. Oh, something else we found on ours (you should check it anyways) was the flexable drain line for the fridge was about 3' too long and shoved up behind the fridge and not allowing condensation to properly drain outside, that was a easy fix. Only issue we ran across to where it warranted a trip to the dealer was the water pump went bad and wanted it replaced while it was still under full warranty which they did and actually upgraded it to a better Sherflo unit. Again, I believe water it the #1 killer of trailers so if you get a new one make sure the roof and seals around eveything up there looks good and touch up as needed and every year and you should be good to go. Good luck and happy camping!
