Full timing FW

Dual pane tinted windows

Two air conditioners

Re-think the washer/dryer - you can do two weeks' worth in 1-1/2 hours in the town laundry...especially helpful if you like public parks. W/D = doing laundry constantly in small amounts. You also need full hookups.

Make sure your truck is suitable to tow the 5th wheel. They are heavy nowadays.

Most 5th wheels considered suitable for full time are 50amp, have w/d prep a second AC, important if you plan on spending time in hot humid areas. A nice option is a dual temp AC with heat pump, which is nice if you're not paying for electric as in most daily or weekly rates.

If you plan on boondocking you will want a generator and/or solar. We went 5 years without a generator, in those five years I could count on one hand the number of times we weren't on hookups, I can also count the number of times we've used it since then.

Again if boondocking you'll want large holding tanks and fresh water tank. If that is not in your future and hookups are your thing no need for mega tanks. We can go a week with our 60f/50g/50b, it's sponge baths and paper plates.

To me carry capacity extremely important. We have 3000 lbs, before water, propane and to me that is the bare minimum.

These are the things I would look for in a 5th wheel but they are the things that are important to the way we travel. Another poster said, make sure you can use the bed, bath and refrigerator with the slides in, not important to us as only the potty needs to be accessible for us as we seldom travel more than 5 hours/250 miles a day and with a good breakfast there,should no need for more than a potty break for both us and the dog.

I hope my thoughts are helpful.

A couple who did a good job of describing their process, and the good/ bad since are RV-Dreams

Just one piece of advice - make sure the wife is very happy with the kitchen area, and she should be happy with the rest of the layout also.

You'd hate to get into a situation where you have to give up one - the wife or the RV.

Expensive to replace either.

But also be aware, very few folks buy the perfect RV the first time. It takes some time living in them to realize what does/ does not work. Sometimes a cheaper used or smaller rig might be best, planning to replace it in three or four years.

Heated holding tanks/ underbelly are pretty standard on non-basic 5th wheels. Generator - depends upon where you will be camping.

Going from a TT to a 5er changes where you can camp. Know a couple folks who went to a TT because their 5er was too tall to fit under trees on many western states forest service and NPS campgrounds. Not just in campsites, but the roads in the campground.

A TT is 11 to 11 1/2 feet high. A 5er is 13 to 13 1/2 feet high. Since you mentioned a generator, I'm guessing you are talking about boondocking quite a bit.

The RV market is changing. One major well respected MFR now equips their models with an induction cooktop and a four door Propane/Electric fridge. I guess they assume everyone who wants the boondocking fridge will be cooking outside.

If you are wanting a washer/dryer - you might not be talking about boondocking. Either a generator or a W/D will add a good bit of weight. Probably don't need both, but your requirements are your own.

See if you can find one that allows for use of the bathroom, stove, frig when your slides are in. Nice to be able to use those things when you stop for a break on travel days. You don't want to deploy slides when just stopping in a parking lot or rest area somewhere.

Spend time looking around. People have different wants and needs. Don't rush a decision.

A big, heavy, expensive one. You probably don't need to make 3 posts about it.
