Nomad 15' - needs floor partially replaced

This little RV has been used by an older man for many years 4 hunting a getaway man cave it pulls easily yes... parts of the floor are very soft...no signs on the ceiling or walls where it leaked in its past few years but it probably had some issue with moisture next to the door because of the floor near the entry... I have all new plyboard that's included... it does not leak I recently multi sealed the roof and all the seams thoroughly... it is a little rough here (entry door is in need of its jam wood frame replaced) but it's a good roof over somebody's head or roughing it camping as Porta-Potty - shower - propane wall convection heat and water heater - sink and small RV refer... not sure if the AC/ heater on the roof works...tires are good condition title in my name and has license to be towed thx for viewing
