We fixed these this week.
1.We popped our city water in spite of regulator. Installed improperly at manufacturer.
2. New nitrogen tire popped with two huge wear holes. Tire issue.
3. Range top. Falls off each time we fold it down. Manufact.
4. Leaked in rain where some stripping under the bunk failed. Manufact.
5. Siding for the tent came undone on both sides of trailer. Manufact.
If you search these threads or just start on one and start reading you will find that these types of problems are common even in MH that cost hundreds of thousands of dollars. That is not defending FR or the dealer for letting that stuff pass out the door... it is just reality in this day and age.
Take control over your new trailer and fix and inspect and embellish it to make it YOUR camper and not the dealers. Hopefully you are handy. Taking things like this back to the dealer will only cost you time (not camping) and gas money. If you can fix it yourself then do it.
Tires are a problem... they are referred to here on this forum as China Bombs. Unfortunately 90% of camper tires are made in China. Picking up replacement tires that have a higher load range (more plies) and a better brand name is usually done in short order by many owners who would rather not be bothered with OEM tire failures on the road. Again... about 5% of the threads on this forum are tire related. Get your tires BALANCED... hardly any tire dealer does it standard... but it makes everything smoother and does not shake your trailer while hauling it down the road.
Range hood hinge problems have been covered on this forum recently. DO a search for the solution.
After I got home I crawled under and over my Shamrock 183 for many hours... improving and correcting many small items (nothing major except bathroom door lock was misaligned allowing door to not stay shut). After all was said and done, I felt like the trailer was now really mine and I knew most everything about it that needed to be known. I also then spent a week driveway camping in it so that I knew all systems were ready to go ON THE ROAD.
This last week I put on Eternabond tape over all the roof seams (HTT 2 years old from production date) so I would not have any roof problems in the years to come. Did I need to do that now? Probably NOT... but I'm glad it is done and water infiltration through faulty or deteriorated roof seams is one thing I can cross off my list at least for the next couple of years.
Read these many threads on this forum and learn from the collective wisdom of many having put many years and miles and have enjoyed their rigs after everything was corrected.
Good luck and good camping ahead!
