I have the non slide version, a 2350LE Sunseeker.
From TT to rv , expect to hear things clanging around inside the rv when you drive. You do not hear all that when towing a TT. It takes a little bit of work to tweak it.
Its rv #11 for us and we really love this rv.
FR and our dealer had an established positive reputation that allowed them to work together to resolve all minor issues. That's a big plus.
It has Azdel walls if that matters to you. It also has VG R-values, it's a very warm rv. Of course your slide model may be a little different. Less R-value in a slide. It also cools off very well using the 15k AC unit at a 99F humid temp.
***ask where the slide breakers and motor are located in case you need to swap it out one day. Ask how to swap out the slide motor, some are very difficult.
I always carried a spare, slide motor, freshwater water pump and LP regulator. They can often be transferred between rvs.
**ask how to manually retract your model of outside awning. It can be a tad difficult to operate one these class C's with the awning and slide stuck in the 'out' position. :)
Our option upgrades .
Serta pillowtop mattress, which is perfect being that we spend 1/3 of our life there.
We also upgraded to a porcelain toilet , where it seems like we spend another 1/3 of our life.
100 watt solar panel on roof plus another 100w as a portable system.
Battery Isolator Manger: Its not just an isolator.
Located behind an access panel at the entry steps , my unit has a BIM to keep the coach and chassis batteries charged while driving. It alternates the 20 minute charge time from one bank to the other.
While plugged into shore power and the cut-off switch turned 'ON' both banks will charge in the same manner using shore power or the generator. Otherwise the chassis batt will die off in a week or so.
That's the reason they installed an emergency start switch under the drivers seat. It activates the coach bank., so you can start the rv
**to use the generator,
I 'do not' have a transfer switch, I have to physically plug into the 30amp power inlet located in the rear most compartment on the drivers side. Just in case you start the gennny and you have no power...plug it in or switch on the transfer switch.
I added a 100w solar panel that keeps all my batts charged 24/7.
It has fully heated water system and easy access heated water pump and by-pass system. The freshwater tank that is under the bed is heated as well as below the sinks. The raised floor in the bed/bath area allows heat to travel E/W from the area below the bed to the bathroom sink. It makes a good 'snowbird' rv from NY to FL.
Make sure you work into the deal a real good positive caster alignment on an E450 front end. The dealers do not align them when they get them on their lot.
I had to spend a few thousand on suspension upgrades to get my Ford to handle better. I would buy it on a GM if possible.
The U dinette is ok for meals but if you want to sit and watch tv or a movie, You might want to look into a dinette mod or set of recliners that will fit in the slide.
