Not beginners, just unsure of what to buy next.

If the only reason you are thinking about buying a 5er is that it is an "amazing deal" then it really isn't. If you are only going two or three times a year, will you ever in the future go often enough to justify the price tag, depreciation, storage and maintenance? Personally, I would rather spend all that extra money going camping.

DH and I are addicted to camping - we spend at least 100 nights a year in ours. If it was only 10-15, I really don't think we would have upgraded.
