Were New to the 5er world we just purchased a Prime Time Sanibel 3601 Residential. We been on the happy trail now going on two years as full time camp host. Which has been interesting to say the least, a lot of wonderful people still out there!I believe i was retired for two months before my finance handed me a application after she had gone for a walk around the camp ground on our maiden voyage with our old TT. Wonderful TT! Hope I am as happy with this unit as i was with that.
