Not to question your plans too much - but finance rates on RVs are amazingly low. You can make more money on a moderate investment than the interest rate on the RV with a 20% down.
Many newer 5th wheel trailers are built to not need slider type hitches, but be sure to ask/ check the manufacturer specs.
I've recently picked up my second Forest River trailer (TT, not 5r) and I've happy with the company products as a good balance between price / features / quality of construction.
It's not an Open Range or a DRV Suites - but FR makes a good trailer (Coachmen is a Forest River owned brand).
