If this 2108TB has LiFePo4 battery, how many amp hours and how what charging system is in it. If it uses the OEM charger, that will work, but it’s not ideal for LiFePo4. I agree with @Eagle5 in that no rv should have a range without a range hood. I don’t agree with him about the fridge. If there are LiFePo4 batteries aboard with a good charging system (LFP profile charger and some solar), a compressor fridge has a lot of advantages over an absorption fridge. After 40 years of rving with absorption fridges, we are happy converts to compressor fridge. We boondock as much as we can. On trips out west that can be as much as 75-80%. We never have concerns about the fridge because we have enough battery and solar to outlast the number of days that our tanks can deliver. Without the right setup a compressor fridge is not suitable for boondocking.
Upside to 2208TB floorplan: You can sit on the beds with the slide in. You may not think about it so much, but once you’re on the road, you’ll be stopping places like rest stops, and some overnights where you’ll want to sit in the trailer without having to put out the slide. You should never sit in the dinette in the slide when the slide is in. Being able to stop and enjoy lunch or relaxation in the rv with slide in is huge. The 2108FB doesn’t afford that option. The 2108 DS does, but in involves having to raise the Murphy bed. We actually like the TB for that reason alone.
Downside to 2108TB floorplan: you lose a lot of pass through space versus a FB or DS floorplan. We’ve found that although we like the TB floorplan, we really wouldn’t be happy with a small pass through. We put our heavy stuff in the pass through in order to balance the trailer, afford the tongue weight we want, and keep our truck bed light. We would be over our tow vehicle Rear Axke Weight Rating, if we didn’t have the ability to load up the pass-thru. Also, I needed the pass-thru space to install our LiFePo4, hybrid inverter/charger and two solar charge controllers. Don’t know if I could have gotten all that gear under one of the 2108TB beds. Plus, if you’re old and fat like me, there would be no way to crawl into the TB pass through.
Some TB owners have said in cold weather camping, they get cold at night because the beds abut the sidewall and if your body touches the sidewall you can feel the cold. I dunno if that’s a biggie or if you can insulate your body from the sidewall.
Just some things to think about before you pull the trigger.
