We too peeled up our old sealant on the roof vents, skylight, etc and went around resealing everything ourselves. Your repairs look great. Hope you and DW get to go camping soon so you can relax and enjoy like you had intended to when you bought it. Now that you will have everything resealed (check around your windows/door too) it will be much easier to maintain each year now that you know when it's been done. You should feel very accomplished at what you've done.
