I grew up camping in pop up campers. So I have a fair amount of experience with the nuances involved. Wetcanvas wet floors being partially inside and outside all at the same time I am comfortable with. I have decided to take the plunge with two young kids 4 and 6 into the pop-up camping lifestyle. Recently I've come upon used pop-up at a dealership that would seem to fit our needs quite well. It has a slide out Dinette as well as a porta-potty shower option. It looks absolutely ideal for our needs. It is an 11 year old Jayco model. Two things concerned me when looking at it at the dealership. The first is the toilet when flushed occasionally discharges a black fibrous like material. The service tech thinks that the toilet wasn't used much and dirt and sediment has collected on the inside. Since that tank is separate from the fresh water holding tank as well as the water inlet for a city hose connection I'm not so concerned about the water quality as I am with the effects of gunky water running through the pump and lines might have. I'm concerned that within short order I will burn up the pump or a line will get clogged with that dirt and debris. The larger concern is water rot primarily at one corner of the roof. The other three sides look literally brand new. However the corner that receives the majority of the runoff from the roof bone and air conditioning unit has water right to the point where it's a little soft along the bottom Edge and the half inch piece of particle board that sits on top of the metal lift arm and attaches to the side panel of the roof is significantly rotted. It is to the point where I'm concerned it may not hold up to regular use of lifting and lowering the roof. The roof also has half-dozen patches from where it looks like a tree limb may have fallen on the top and punctured the roof. Although after crawling around it feels quite solid. Is this type of wood rot inevitable with the purchase of a 10 year old popup? The dealership has offered to reduce their asking price to $4,500 4 the Jayco 1206 model. They've also said that the side plywood could be replaced at the cost of $1,000 or less. Does anyone have any general thoughts regarding this damage, it's repairability, or the thought that some water rot on the roof is an editable when buying a used 10 year old popup which the salesman kind of indicated was the case.
