I have been debating the same thing myself....35ft trailer or 35ft fifth...I lean towards the fifth for shorter length on the road, in the camping spot, better towing characteristics and roomier feel to the layout. However I also lean a bit towards the trailer due to keeping the bed for a quad in there and other gear.
I don't have a quad so that could easily be a game changer, but with regards to all the "Stuff" that was our concern too when we made the decision on a 5er last August over a TT. I was shocked to see I could fit all my "Stuff" in the 5er rather easily. This resulted in not having to crawl into the cap and load up the bed of my truck with it and empty it after every trip into the garage.
I still have room in the bed for items such as firewood, large cooler between the hitch and cab, etc.
And no more arguments with the wife when hooking up :W
And for the OP, the added bedroom slide in the 5er will make it so much nicer for moving around, along with the normally better tow characteristics of a 5er vs a TT of that length. If you travel a lot, if you park it for the summer that's not much of an issue.
Returned from Florida today (no trailer in tow), but was stuck in a 6 mile back up yesterday on I-75 NB. This was between a 75 and 90 minute crawl for a 1/2 mile project that has 75 down to one lane. The handy DOT sign blinking advised me of a detour to take, while I was stuck in the backup, not real helpful, since everyone was getting off at the exits and that was backed up too. The detour referenced looking at a map, makes me think it had me leaving 75 near Knoxville, thus avoiding the nightmare of traffic we faced or on the nearby roads that others exited too.
From what I recall it was Hwy 62 to US27 North to Hwy 63 to get back to I-75. Had I known of this I would have used it traveling on a late Friday. Off times is probably not a bid deal at all. Just figured I'd pass it on! I'm not familiar with the area and can't commenton the roads or the best reroute. Maybe someone will add solid info on a reroute.
Here's the DOT statement, but lacks the detour that was playing on the AM radio station:
Updated 04/21/2014: Beginning Monday, April 21, 2014 at 7:00pm: I-75 northbound will be reduced to one lane until approximately May, 20, 2014. During this time the Interstate 75 will be reduced to one lane northbound at exit 134 in Caryville to complete necessary bridge repairs. At exit 134, the left lane only will continue north I-75 and the right lane will be required to use exit 134. Southbound I-75 in this project will be unaffected until a future date in May or June 2014. Motorists are encouraged to be alert, observe posted speed limits, watch for stopped vehicles, and obey guide signage. Please drive carefully when traveling through this area.
