Hi Jim,
We need to know the year and model of your camper to help better. The 13 1/2 is a model number but folks also sometimes call out a generic length as to what they have. We just need to know what it is you have. And if you do not know what it is, post pics of all sides and can back into it.
Sunline, they were unique and in my mind, and many others who have been associated with the brand a while, they are a great camper! And they were built better than most. This post has some background on the company with our Wiki post.

Tires, again need to confirm what trailer you have to help better but I can say this generically. Tire OD may be an issue going to 14", top of tire to bottom of wheel well is one concern that will most likely interfere first if it will. You will need to measure what you have now and let us know. If there is clearance tire to tire at the center and wheel bump clearance at the wheel well, they the 14" might work.
BUT some folks have raised their camper with what is nicknamed "an axle flip" It means the underslung axle from Sunline was moved from the bottom of the spring pack to the top, (Over/under) and that lifted the camper several inches to help with dragging the back of the camper over most anything. Gas stations drop offs as a starter. If yours by chance had that lift done to it, then the tire OD may not be an issue. If you post some pics of the axle and springs and the side of the camper we can see what it is you have.
Brakes. Odds are high it came from Sunline with electric brakes. Even their tiniest camper at 2,100# GVWR Sunpsot had electric brakes. So yes you need to add a 7 wire plug to your tow vehicle if it does not have one and a trailer brake controller. That an a battery on the camper and an emergency breakaway switch if it does not have one.
These are somewhat generic quick answers, but should help get you going to ask even more questions. So ask away!
Hope this helps
John
