It took me about 3 weeks to get on to using the site , when I first started.
The dark blue bar , across the page , will appear in every forum you go to , and clicking " User CP " on the left end,will take you back to a list of your posts , no matter where you are in the site. Kind of an escape to known territory, safe zone.
I've only used the site with a laptop, so if your accessing the site with a smart phone , I can't provide any info on that.
As far as the unit your looking at , I've never been in one , and only seen a few over the years. I believe they were very easy to over load, and low on power , due to the limits of the chassis. The price seems high to me , for a 25 year old, small unit . For that price the rig would have to be perfect . With new tires and batteries, no signs of water leaks, and all RV systems operating perfectly. I don't have access to a , blue book for USA prices, but I'll do a search for others for sale to see what they're priced at.
