Congrats on your new Sunny and welcome to the group! I see you are a fellow Ohioan! Great. We are more central Ohio near Delaware, Ohio.
Do you know what model number your camper is? It would be a T-XXXX 4 digit number.
For your question on hints on maintenance and care of the camper. We have a lot of info on our site which we can point you too.
Did you get a copy of the Owners Manual that came with the camper? For your 2005, this would be a large white 3 ring binder with the big Sunline logo on the front. There is some general info in there which is a good place to start.
Here on the site we can and have gone into more depth in most cases beyond the generic owners manual.
There are sort of two mechanical areas that you might not know about that I will mention. And we do not know if you would be doing them or having someone help you with them, but the biggest thing is to know about them so they can be taken care of before issues come.
1. Tires, wheel bearings and brakes. This is an area to understand before a breakdown on the road happens. The trailer tires are a subset of this area and need to be in good condition for a trailer tire and they need to be checked for correct tire pressure at the start of each towing day. Unlike auto tires, trailer tires most often will as we call it, "age out" before they wear out and they need special caring that is different from an auto tire that rolls each day. On an auto tire, it is common to look at the amount of tread left to know it's time to change tires. On trailer tires, age of the tire is a big deal as most folks do not put on enough miles in a year to ever wear them out. 5 years on a ST trailer tire can be about all that can be expected to give good service. As the tires age, the rubber starts breaking down, cracks form in the side walls and between the treads. And the whole tire also ages with slow degradation. Most trailer tires have a speed rating of a max of 65 mph. Going over that for a period of time causes excess heat and accelerates the break down process. This topic is something more to research as a tire failure can make for a bad day camping.
There are DOT date codes stamped on the side of each tire. Here is an article on how to read them. Some times the codes end up on the inside of the tire and you have to crawl under the camper to see it.
The axle bearings need grease and brakes also need routine adjusting and servicing. Do you know the last time they were done?
2. The next area is what is proper roof care and maintenance for your camper rubber roof. Unlike home roofs that do not need much maintenance once installed, camper roofs need constant routine maintenance. Just because you do not see any leaks inside the camper (a good thing) this does not mean the roof is properly cared for.
The roof needs to be cleaned and washing of the roof should occur 4 times a year to remove the dirt and other things that get attracted to the roof.
And a big one, the sealants around every roof seam and opening on the roof needs to be checked for tiny cracks and splits. This should follow the same 4 times a year check with the most important check being late fall before winter and early spring just after winter. Most roof leaks start with a flaw in the roof sealants/caulking. And there are special brands of caulking to use to treat these splits/cracks. This thread is a good start on how to service your roof sealants. Also your roof is not a direct walk on roof without taking special precautions to spread the load of standing on it. There where very few Sunline direct walk on roofs unless that option was special ordered at the time of manufacturing. The process is mentioned in this link. http://www.sunlineclub.com/forums/f7...1-a-11508.html
The item mentioned above should get you started. There are more topics that will come in time, battery maintenance, spring start up, winterizing for freeze protection, water system sanitizing, cleaning the camper etc. Surf our site and ask away on things you need more help with understanding.
The biggest thing you need to do, is have fun camping!!!
This helps you get past the needed routine things (aka work...) to keep your camper in top shape and leak free.
Hope this helps
