You will have some problems, but you won't have all the problems that you're reading about unless you have a fleet of Rpods!  Remember that you're seeing problems related by many Rpod owners.  Any  one owner is not going to have all those problems.

I have not had any major problems (other than a frozen toilet valve due to my own poor winterizing).  Just loose screws.

While it does appear that build quality has suffered in the past couple years it is also noteworthy that those of us like Jim (poston) tend to be quiet on problems because they simply haven't many, can simply fix it themselves, or see it as regular maintenance as with any item that we own.

Those who do have problems will be quick to post and complain to let others know how cheaply these travel trailers are assembled but also come on this forum to get helpful advice from others who have traveled this path before and are able to assist in a solution.  Personally I have been blessed with the 177 that has been almost trouble free for the 11 years of ownership.  Yes, a replacement Dometic fridge was purchased when the original decided to 'retire' after nearly 10 years but I have been told that is about the normal lifespan of that style of refrigerator.  And yes, I had to retire one of my original 12v batteries last August with a Trojan T-1275, but I really cannot complain as the one replaced (Interstate group size 24 deep cycle 12v) would have turned 11 years in another 5 months.  The other original battery will turn 11 years old next month and has held a charge over the winter very nicely.  It has not been charged since November 1, 2021 and yesterday I checked it and the reading was 12.38 volts, not too bad after sitting on a cold concrete floor in an unheated garage in northern Michigan for 19 weeks.

That is one of the great things about this forum which I have benefited from many times, being able to bring an issue or concern and getting good advice from those who know a lot more than me.
