Hello World...Dweller 15 owner here...purchased last summer at ROA in Utah, only a couple of trips take so far. This forum has been invaluable as a source of information and for commisery of my frustrations with the camper (which I do love).
The batteries suck. The front box struts died over the winter. One of the cabinet latches came apart on the backside of the door. (anyone know where to find that hardware?) It is dusty, especially under the bed. The overall lack of documentation is frustrating.
On the bright side...mine tows fine with no modifications up to 75mph on I-80 from CO to CA. My tow vehicle is a 2003 F250 6.0 Diesel longbed, so I think I'm just telling the trailer who's the boss, although I haven't observed the rocking that so many have noted, which should be tow vehicle agnostic.
Yesterday I swapped out the batteries for lithiums. I seemed to have left the inverter turned off after putting the camper under a car port for the winter and the stock batteries were dead. I found them so lacking that this mistake may have been my subconscious just taking matters into its own hands. Regardless, I'm upgraded to lithiums now. I went with Renogy's for the irrational reason to keep the system in brand. I got the self-heating units as I live in the Eastern Sierras and will do some winter camping. Probably unnecessary, but it feels comforting.
NOTE: The owners manual of the battery asserts that the self-heating function requires an MPPT controller. Of course, I didn't read that in advance of the purchase and the Dweller has a PWM controller. Upgrading to an MPPT has its inherent advantages, so that's on the list now, I guess.
Next, I want to add a bit more solar, and will either be putting another panel on the roof or using the Renogy suitcase. I like the suitcase idea, especially if there is a direct plug point on the camper. Multiple posts on this thread have mentioned an Anderson plug or other wiring at the tongue that goes to the batteries, presumable to support DC-DC charging from the tow vehicle. I can't find such a plug/wire on my tongue. Is it on all Dweller configurations? If so where exactly would I find it? There aren't that many places to hide, so I'm thinking I don't have one.
I've ordered replacement struts for the front box from Amazon for only $15. I'll post a link if they work.
Thanks for all the great advice and information from the members. Truly helpful, even if I never would dare to drill a homemade supercharger into my camper to control dust.
