Prepurchase repair recommendation necessary?

[rsy]

I have paid for an inspection on the '08 Prowler mentioned earlier. RV repair place says Prowlers windows are installed with foam to prevent leaks, which they say should be either sealed (less optimum choice) or removed and packed with putty at $90 per window. Since the cost may blow the purchase deal, isn't sealing a reasonable and cheaper option and if I checked the seals regularly after purchase isn't this a decent longer term solution as well?

I can't see the need to remove and pack window openings with putty. They may be removed and re-sealed with butyl tape for just a few dollars per window if you are a handyman type. This is what many trailer mfgrs do anyway. Probably take near hour per window counting removal, cleaning all old sealant away, placing butyl tape and re-installing window.
