dq72---yes keep an eye on the caulk. Bob---I'll use Dawn from now on---a lot cheaper. TT was bought Feb.2010. Have no more than a dozen trips on this unit. All trips within an hr of home with the exception of one which was 3 hr. Obviously we can not compare a home and TT roof but when the manufacturer hypes up such quality in materials and build...........then in turn uses such an inferior method/material in this construction??? My point is "they" glob the sealant around the vents, antenna, and skylights like a blind man was their mentor but the places that will obviously flex,bend,move by design the caulk is barely adequate to cover the gap. Heartland uses aluminum frame and fiberglass skin(Latest and greatest--laminated construction--see their Edge website) for its construction but for a most critical part in its overall constuction they still use in my opinion an inadequate method of sealing the roof. Use Eternabond or a like product and be done with it from the factory. I'm not going to believe it is not used because of cost or labor. I paid almost twice what I should have for the Eternabond because I wanted it now. One minute on Ebay and I found it for $30 less than what I paid for it. As evidenced above the way sealant is applied, if the factory switched over to an Eternabond like product this wouldn't slow them a bit. I bought a "New" trailer to camp with not work on. I find $92 an hr a bit hard to swallow to apply caulk virtually every year. I bought an 18K new TT, not a 10K 5yr old TT. I'm familiar with sealing and maintenance as I retired from the AF/Air National Guard working Aircraft Fuel Sytems on F-16's for 23+ yrs. Sealing integral fuel tanks,pulling/installing wings........... I wish the manufacturer would live up to its advertising---"peace of mind that you will spend more time enjoying your family and travels than worrying about repairing your rv." Hey, this probably all for naught as the Edge is history...........My 2 cents.
