I have heard some good things about Funtime but no direct experience. I have dealt with several dealers in the past and honestly, once they get your money they seem far less interested in being helpful! The service and repair departments always seem to be even less helpful and often inept. They push through repairs and hope it works long enough to get the unit out of warranty.
It is helpful to be somewhat handy if you have an RV as something will always break, leak or come loose. A big empty box being bounced down the road and jostled around by wind for hours on end is pretty hard on things. Even the most expensive RV’s are still built in a fairly simplistic manner - they just have a prettier skin over everything. They pretty much all source appliances and other equipment from the same places although there are different levels of quality in some brands. You may see the same refrigerator, stove or furnace in units that are tens of thousands of dollars apart in price. They try to reduce weight anywhere they can but this can cause structural issues with more flex and movement. It is a balance and some are better at this than others. Knowing that they all use similar “guts”, I have always focused on the quality of the structural design and materials as everything else can be replaced fairly easily.
So, now that I got all of my negative energy out - I will weigh in on brands. We did a ton of searching and checked out at least fifty smaller trailers last year before purchasing one. ( I tend to over research and plan) We were looking for a little bigger one than you might be looking for though. We wanted something less than 25 feet but also with plenty of storage and well thought out floor plan. We ended up purchasing a Rockwood 2504s (made by Forest River) This is a very large floor plan in a small trailer. It has a slide out for the large dinette which adds a ton of room and a queen murphy bed that quickly and easily folds away revealing a full size couch during the day! The build quality overall seemed above average and reviews were generally good. Even so, we have had issues with leaks in external access doors (dealer took six times to fix and even then they did a poor job), loose plumbing, sub par wiring, etc.
Knowing RV’s and what to expect, I took it all (mostly) in stride and corrected the deficiencies my self. We love the trailer and it has served us well so far.
As far as backing up, I have heard the 4 and 8 idea before and if someone showed you I think it would work fine. What my dad taught me, and I still use today, is that which ever way the BACK of your front tires are pointing is the direction your trailer will go.
