When we first got ours in April of 2010, the biggest thing I'd ever pulled was a 16' flatbed trailer. Quite a difference going from a 16' flatbed to a 30' 5th wheel! We went from a tent to a 5th wheel. Talk about nervous! I didn't pick it up from the dealer for a couple of weeks because rain was in the forecast on the days I wasn't working & I didn't want to pull it in the rain the first time out. First few trips I really didn't even want to change lanes! Now after a little over 30,000 miles it's not nearly as bad as the first few times pulling it. I've even gotten to the point that sometimes I'm pretty decent backing it into a campsite! Just like anything else it takes plenty of practice. Best advise I could give you is like others have said, do a good PDI, and check out all the plumbing to make sure it's tight. Also you might look through the past posts on here, and on other forums. Before we got ours I was on about 3 forums, even if someone is talking about a motor home, the systems are for the most part the same. Now I hardly look at the other forums, just check this one. I learned a lot about RV's and the lifestyle by reading the forums. We aren't full timers, but are any timers & it averages out we live in it about 6 months out of the year.
